Keltsvian

Keltsvian is a language isolate which has an uncommon grammar and Indo-European influence in vocabulary. The autoglotonym is keltsvan [keld.svan].

General information
Keltsvian is a language spoken in Keltsvia -a fictional country in Eastern Europe-, the word stems are mainly taken from Proto Indo European. The grammar has the following characteristics: non noticeable stressed syllables, no grammatical genders, singular and plural numbers only affect to nouns, verbs and personal pronouns, simple patterned grammatical cases and it has some degree of vowel harmony.

Consonants

 * The phoneme /m/ is always represented by the grapheme m.
 * The phoneme /ɲ/ is always represented by the grapheme ň.
 * The phoneme /s/ is always represented by the grapheme s.
 * The phoneme /z/ is always represented by the grapheme z.
 * The phoneme /ʃ/ is always represented by the grapheme š.
 * The phoneme /ʒ/ is always represented by the grapheme ž.
 * The phoneme /l/ is always represented by the grapheme l.
 * The phoneme /ʎ/ is always represented by the grapheme ł.


 * The phonemes /ɱ/ and /n/ are always represented by the grapheme n. The phoneme /ɱ/ is pronounced when n is written before another labio-dental consonant. The phoneme /ŋ/ is represented by the digraph ng at the end of the word or by the grapheme n when it is written before a velar consonant. In the rest of cases where the grapheme n appears, /n/ is pronounced.
 * The phoneme /p/ is pronounced when the grapheme p is written and when b is written at the end of a word.
 * The phoneme /t/ is pronounced when the grapheme t is written and when d is written at the end of a word.
 * The phoneme /k/ is pronounced when the grapheme k is written and when g is written at the end of a word.
 * The phoneme /b/ is only pronounced when the grapheme b is written at the beginning of a word, after a nasal consonant or when the grapheme p is written at the end of a syllable that it is not the last syllable of the word. When b is not written at the beginning of a word, at the end of a word or after a nasal consonant, the phoneme /β/ is pronounced.
 * The phoneme /d/ is only pronounced when the grapheme d is written at the beginning of a word, after a nasal consonant or when the grapheme t is written at the end of a syllable that it is not the last syllable of the word. When d is not written at the beginning of a word, at the end of a word or after a nasal consonant, the phoneme /ð/ is pronounced.
 * The phoneme /g/ is only pronounced when the grapheme g is written at the beginning of a word, after a nasal consonant or when the grapheme k is written at the end of a syllable that it is not the last syllable of the word. When g is not written at the beginning of a word, at the end of a word or after a nasal consonant, the phoneme /ɣ/ is pronounced.
 * The phoneme /ts/ is always represented by the grapheme c, but when this grapheme appears at the end of the syllable the phoneme /dz/ is pronounced instead. In some loandwords, the dygraph dz can appear and it is represented by its IPA value.
 * The phoneme /tʃ/ is always represented by the grapheme č, but when this grapheme appears at the end of the syllable the phoneme /dʒ/ is pronounced instead. In some loandwords, the dygraph dž can appear and it is represented by the phoneme /dʒ/.
 * The phoneme /f/ is pronounced when the grapheme f is written and when v is written at the end of a word and the phoneme /v/ is always represented by the grapheme v.
 * The phoneme /x/ is pronounced when the grapheme x is written and when h is written at the end of a word and the phoneme /h/ is always represented by the grapheme h.
 * The phonemes /r/ and /ɾ/ are always represented by the grapheme r. The first phoneme is pronounced when r is written at the beginning or at the end of a word, in the rest of cases, the second phoneme is pronounced.
 * The phonemes /j/ and /w/ are always part of diphtongs or triphtongs, they always appear after or before a vowel. Keltsvian linguists consider these phonemes as weak vowels because they are always accompained by strong vowels.
 * /j/ is represented by the grapheme j and it is part of the diphtongic graphemes á [ja], é [je], ó [jo], and ú [ju]. Its strong vowel counterpart is i /i/.
 * /w/ is always represented by the grapheme w. Its strong vowel counterpart is u /u/.

Vowels

 * The phonemes /a/, /e/, /i/, /o/ and /u/ are represented by the graphemes a, e, i, o and u respectively. The phonemes /a/, /e/, /o/ and /u/ are also pronounced as a part of the dyphtongic graphemes á [ja], é [je], ó [jo] and ú [ju] respectively.
 * The weak vowel counterpart of /i/ is j /j/ and the weak vowel counterpart of /u/ is w /w/.
 * /a/, /e/ and /o/ are considered pure strong vowels because they do not have weak vowel counterparts.

Hierarchy of vowels
Within each syllable in Keltsvian language, it exists a hierarchy of vowels in 5 levels:
 * 1st level or pure strong vowels: /a/, /e/ and /o/.
 * 2nd level or unpure strong vowel: /u/.
 * 3rd level or bastard strong vowel: /i/.
 * 4th level or royal weak vowel: /w/.
 * 5th level or bastard weak vowel: /j/.

There are also 4 rules regarding the hierarchy:
 * 1) In all syllables there is only one strong vowel of any kind.
 * 2) When a pure strong vowel is accompained by another vowel, this one can be only pronounced with any kind of weak vowel.
 * 3) The unpure weak vowel can only be pronounced with the bastard weak vowel.
 * 4) The bastard strong vowel can be only pronounced just right after the royal weak vowel or along any pure strong vowel or the unpure strong vowel.

Diphtongs and triphtongs
Applying the rules of the hierarchy of vowels, in Keltsvian there is the following diphtongs: /aj/, /aw/, /ej/, /ew/, /oj/, /ow/, /uj/, /wi/ and /wo/ always represented by the graphemes aj, aw, ej, ew, oj, ow, uj, wi and wo respectively.

As explained above, the diphtongs /ja/, /je/, /jo/ and /ju/ are represented by the four diphtongic graphemes á, é, ó and ú respectively.

According to the rules of the hierarchy of vowels we cannot find the following diphtongs in Keltsvian language: /ij/, /iw/, /ji/, /uw/ or /wu/ as diphtongs.

Triphtongs are always formed by the same structure W-PS-W, where W is any weak vowel and PS is any pure strong vowel. The unpure and the bastard weak vowels have no use in triphtongs. So all the possible triphtongs are: /jaj/, /jaw/, /jej/, /jew/, /joj/, /jow/, /waj/, /waw/, /wej/, /wew/, /woj/ and /wow/ represented respectively by áj, áw, éj, éw, ój, ów, waj, waw, wej, wew, woj and wow.

Phonotactics
The possible syllables in Keltsvian one of this two structures (C)(C)(V)V(V)(C) or (C)(V)V(V)(C)(C). The nucleus is always a strong vowel (/a/, /e/, /i/, /o/ or /u/). The optional vowels are always weak vowels and they are present in diphtongs and triphtongs, always applying the vowels hierarchy rule as we saw above. The onset, when present, is formed by one or two consonants, as well as the codas. When the onset is formed by two phonemes, the coda only has one phoneme and vice versa, so in one syllable there is never more than three consonants and never more than two consonants pronounced together.
 * No consonant phoneme is duplicated in the same onset or coda.
 * Consonant phonemes that never allow clusters and can be found as onset or coda: /l/, /m/, /n/, /r/, /z/ and /ʒ/.
 * Consonant phonemes that never allow clusters but can be found only as onset: /h/, /ʎ/, /ɲ/, /ts/ and /tʃ/.
 * Consonant phonemes that never allow clusters but can be found only as coda: /ɱ/.
 * Consonant phonemes that may allow clusters and can be found as onset or coda: /b/, /d/, /f/, /g/, /k/, /p/, /s/, /ʃ/, /t/, /v/ and /x/.
 * Consonant phonemes that may allow clusters, can be found only as onset and never appear in the first syllable of a word: /β/, /ð/, /ɣ/ and /ɾ/.
 * Consonant phonemes only present in clusters: /dz/ and /dʒ/. Both only appear as onset in loanwords.
 * Consonant phonemes that follow the hierarchy of vowels rules: /j/ and /w/. If those appear, they are always part of the nucleus, they cannot be part of the onset or the coda.
 * Clusters allowed both as onset or coda: dz and dž.
 * Clusters allowed only as onset: bl, br, dr, fl, fr, gl, gr, kl, kr, pl, pr, sl, sm, sn, st, št, sv, tr, vr and xr.
 * Clusters allowed only as coda: lt, mt, ng, nk, rg, sg and sz.
 * Any other kind of cluster not appearing in this list is not found.
 * The only digraphs are: dz, dž, ng and sz. The last digraph is used in the imperative mood of verbs and the pronounciation is a long s /s:/.

Stress
Stress in Keltsvian is not clearly marked when pronounced. There is no dominant stress syllables in any word.

Alphabet
The Keltsvian language is written using the Keltsvian alphabet, which is the Latin script with 9 additional letters and without q and y, for a total of 33 letters. The additional letters are: á, č, é, ł, ň, ó, š, ú and ž. The native names for the letters is simple: the vowel are named the same way they are pronounced and the consonants follow this pattern: consonant + e. So the letters é and j have the same name, to distiguish them, Keltsvians say: é lur Ésu (é of Jesus) and j en áj (j in yes).

Orthography
Keltsvian orthography is such that the pronunciation of most words is unambiguous given their written form, with very few exceptions explained above.

Conventions
Apart from the rule of the hierarchy of vowels, Keltsvian has also ortographic rules.
 * No double letters, with exceptions in foreign words like picca (pizza) or ázz (jazz).
 * mf is never allowed between syllables, m has to be replaced by n.
 * ts will always become c unless each letter is located in a different syllable, that happens when c is not in compliance with the phonotactics rules. A very good example of this is the homonym of this language: keltsvan, here it is allowed because ts is not acting as a digraphs and it is splitting the word in two syllables. In that example t and s are not part of the same syllable.
 * j will never be written after or before i.
 * j cannot be written before a, e, o and u. á, é, ó and u are used instead.
 * j cannot be written between c, l, n, s, d and the vowels a, e, o and u. In that case, c, l, n, s, d and j will merge becoming č, ł, ň, š and ž. When this consonants are present á, é, ó and ú are not allowed but they have to be used when the rest of consonants are involved.
 * w will never be writter after or before u.
 * When the same vowel is repeated due to the addition of preffixes or suffixes, h is added in between. For example: kohoperaci (cooperation). This rule is applied in all plural forms of nouns ending with a vowel. See below Number section.
 * Only adjectives and some numbers (penk, sek, dek) end with -k.
 * The use of apostrophe (') only applies in the genitive case of some personal pronouns (see below).

Capitalization
Capitalization in Keltsvian occurs at the beginning of every sentence, after a question mark, exclamation marks and in given names, including people, pet names, days of the week, months, planets, moons, stars, constellations, toponyms (cities, countries, mounts, rivers), the first word in the title of a book, song or movie and acronyms.

Foreign words
Keltsvian is generally a conservative language, rarely adopts foreign words and usually they are adapted ortographically and phonetically to the language. Even the other languages' given names are often adapted, like Džordž Buš for George Bush or Hari Poter for Harry Potter. More examples include vudbal (football), vebsajt (website), poranagav (airport, from pora + nagav, meaning air + port), picca (pizza), krwasan (croissant), telefon (telephone), taksi (taxi), údo (judo), óga (yoga), páno (piano), džins (jeans)...

Grammar
Keltsvian is a grammatically inflected language and it lacks articles. Verbs are marked for tense, aspect, mood, person and number. There is no grammatical gender and the numbers are singular and plural. Personal pronouns are inflected for person, number and case. Nouns are inflected only according to case and number and the inflections only vary depending on the last letter of the noun. All nouns have the same final letter in their respective singular and plural form, that makes inflections simpler. Adjectives are only inflected according to case. In Keltsvian also exists a hint of vowel harmony only affecting to plural form of nouns, adjectives and some personal pronouns.

Basic word order
The basic word order of Keltsvian language is SVO (subject, verb, object). The inflections in this language allow a little bit more of flexibility in the order, but this flexibility is not used in daily speech, only for poetry or literary uses.

Nouns
In Keltsvian, nouns do not have a grammatical gender of any kind and they ar inflected according to number and case.

Number
To obtain the plural form of a noun the general rule is to repeat the word from the last vowel. For example:
 * brotar becomes brotarar, meaning brother and brothers respectively.

When the last letter is already a vowel, h is added in between following the orthography rules. For example:
 * mata becomes mataha, meaning mother and mothers respectively.

Plurals are affected by the vowel harmony, but this is only visible when the last vowel of the singular form of a noun is a weak vowel (j or w), in this case the weak vowel is not repeated, the used vowel is the weak vowel counterpart (for j is i and for w is u). This also happens when the last vowel is a diphtongic vowel (á, é, ó or ú). Examples: It is important to know that vowel harmony works in a different way in adjectives (see below).
 * fewt becomes fewtut, meaning country and countries respectively.
 * údeóm becomes údeómom, meaning command and commands respectively.

When a number appears clarifying the quantity of objects the noun is, the plural is not used because is not necessary. For example:
 * ojn kat, du kat; meaning one cat and two cats respectively.

A plural is used to explain that there is no specific amount of this noun but there is more than one.

Case
Grammatical cases are in decline regarding the evolution of this language, there are 13 different cases and some of them are merged as well as 6 declensions.

The Keltsvian grammatical cases are:
 * 1) Nominative (nominativ): representing the main subject of the sentence and consisting in the bare form of the word.
 * 2) Accusative (akusativ): indicating the direct object of the verb.
 * 3) Dative (dativ): indicating the indirect object of the verb.
 * 4) Ablative (apotiv): the movement from a place to another or change from one situation from another.
 * 5) Genitive (luritiv): indicating possession.
 * 6) Causative (ókitiv): indicating the reason, the because of the sentence. Being merged with the temative case.
 * 7) Comitative (komitiv): indicating the company, the with of the sentence. Being merged with the instrumental case.
 * 8) Instrumental (gagitiv): indicating the way something is done, the by of the sentence. Being merged with the comitative case.
 * 9) Lative (anativ): indicating the arrival from a place to another or a change to a new situation from another.
 * 10) Locative (enitiv): indicating an specific place or localization in space. Being merged with the temporary case.
 * 11) Privative (ňewtiv): indicating the absence of some element, it is the opposite of the comitative case, the without of the sentence. The use of this case is also the Keltsvian equivalent to the suffix -less.
 * 12) Temative (peritiv): indicating the topic, the about of the sentence. Being merged with the causative case.
 * 13) Temporary (ómitiv): indicating an specific localization in time. Being merged with the locative case.

The plural and the singular forms of each noun are inflected using the same declension because they finish with the same letter. Some inflections do not modify the noun due to the evolution of this language on the way to lose the grammatical cases, for those cases it is mandatory to use prepositions -when existing- (in these tables, the prepositions will appear between brackets). The Keltsvian declesions are:
 * 1st declension, consonant or 0 declension: applied to nouns ending with consonant. The adjectives only use this declension because all of them end with -k (see below).
 * 2nd declension or A declension: applied to nouns ending with a or á.
 * 3rd declension or E declension: applied to nouns ending with e or é.
 * 4th declension or I declension: applied to nouns ending with i or j.
 * 5th declension or O declension: applied to nouns ending with o or ó.
 * 6th declension or U declension: applied to nouns ending with u, ú or w.

Consonant declension
It is the most common declension because the majority of Keltsvian words end with consonant. In the example the used word is kat (cat).

A declension
In this example, the used word is mata (mother).

E declension
This declension is not very common, very few words end with -e. In this example, the used word is dage (dagger).

I declension
In this example, the used word is diri (tree).

O declension
In this example, the used word is oko (eye).

U declension
In this example, the used word is vatu (father).

Adjectives
In general, adjectives are derived from nouns, like xajsok (beautiful, handsome) which is derived from xajso (beauty). The general rule is adding the adjective suffix -k to the noun and for nouns ended with consonant, applying the adjectival vowel harmony, which is different that the one in plurals. Vowel harmony in adjectives have as difference the last strong vowel (a, e, i, o or u) and they ignore the weak vowels (j and w). For example:
 * fewt becomes fewtek, meaning nation and national respectively.

Colours have not the adjective suffix and they can be used as both nouns or adjectives.

Keltsvian adjectives have the following characteristics:
 * They always go after the noun they modify.
 * They do not agree with number and gender, only with case.

Adjectival declensions
The adjective will always have the same grammatical case as the noun they modify. Adjective declensions are exactly the same as noun declensions. They use the first or consonant declension due to their ending (-k), only colours may use other declension (depending on their ending, like nouns).

Comparative
There are two suffixes for comparative adjective, the less suffix (-puk) and the more suffix (-xek), the second one is equivalent to the English comparative suffix -er. Examples:
 * xajsok becomes xajsokpuk, meaning beautiful and less beautiful repectively.
 * xajsok becomes xajsokxek, meaning beautiful and more beautiful repectively.

Superlative
It is formed just by adding the suffix -uk to the adjective. For example:
 * xajsok becomes xajsokuk, meaning beautiful and the most beautiful respectively.

Adverbs
Keltsvian adverbs are derived from the adjectives. To form them, the only way is to take an adjective and use its instrumental inflection form. For example:
 * xajsok becomes xajsokom, meaning beautiful and beautifully respectively.

Pronouns
Keltsvian pronouns in some ways work quite differently from their English counterparts. They are not gendered and the only kind of pronouns that are modified by case, person and number are the personal pronouns.

Personal pronouns
Personal pronouns in Keltsvian have distinct forms according to case, person and number. Keltsvian is a pro-drop language with respect to subject pronouns. These pronouns are inflected following a different pattern compared to nouns and adjectives. They are the only inflected pronouns. Personal pronouns that use apostrophe are atached at the end of a noun. Following the noun rules of vowel harmony when the last letter is a consonant. For nouns ending with a vowel, the modification of the apostrophe personal pronouns is not needed. Examples:
 * bal +  'lih = bal'alih, meaning their ball's.
 * vojg +  't = vojg'it, meaning your farm's.
 * oko +  'lih = oko'lih, meaning their eye's.
 * diri +  't = diri't, meaning your tree's.

Demonstrative pronouns
There are only three demonstrative pronouns, and they always are placed after the noun.
 * Near the speaker: gi (this).
 * Near the listener: ej (that).
 * Far from both the speaker and the listener: gé ("over there").

Relative pronouns
The pronoun kis is some sort of pronoun for almost every use, it can be translated as that, which, who and whom depending on the sentence. Examples: The word kis is also the interrogative equivalent to what and which.
 * Pul kis kudazu egu bagák = "The chicken [that] you gave me was fried"
 * Pul, kis kudazu egu, bagák = "The chicken, [which] you gave me, was fried"
 * Tetaha kis he esmozli fewte gi esmozli awtakarar = "People [who] is not from this country are foreigners"
 * Vir ej, kis kunoskoze kudoxos, arxitektar = "That man, [whom] I knew yesterday, is an architect.

Sometimes we can use the word ká, but this one is only used for people, being the previous one preferably used for objects. Examples: The word kis is also the interrogative equivalent to who.
 * Tetinin ruksagagom, ká kwesmozli buse, dudek = "The children with the rucksacks, [who] were in the bus, were twenty"
 * Li cena ká kudaze alxos = "She is the woman [to whom] I gave the money.

The word kodej can be used instead of other relative pronouns when location is referred to. The word ankodej is a variant that can be used when motion to the location is intended and the word apkodej can be used when motion from the location is intended. Respectively they are equivalent to where, where to and where from and they also are used in questions. Examples: The word kalis can be used instead of other relative pronouns when manner is referred to. It is an equivalent to how or the way. It is also used in questions. For example: The word óm can be used instead of other relative pronouns when manner is referred to. It is equivalent to the word when. It is also used in questions. Examples: The word apoká is the Keltsvian equivalent for the word whose and this one can be also found in questions. For example:
 * Blis kodej esmoze = "The city [where] I am"
 * Zéjmoze blise ankodej li esmozi = "I am going [to] the city [where] he is"
 * Kwejmozi apkodej zéjmoze = "He came [from where] I am going"
 * Kalis tu kudetisizu lin = "[How/The way] you did it"
 * Awguste, óm tetaha luruzli vakancihi, blis késmozi tetahis = "In August, [when] people have holidays, the city will be empty (lit. without people)
 * Eg pisgize óm he veregeze = "I fish [when] I don't work"
 * Aleksandar studar apoká pungung ajves bilisik = "Aleksandar is a student [whose] grades are always good"

Interrogative pronouns
Keltsvian has 10 interrogative pronouns, the majority of them have their relative pronoun equivalent as shown before. The answer to these interrogative pronouns is made by one of the grammatical cases. Examples:
 * anká: equivalent to to who. The answer uses the dative case.
 * Question: 'Anká kudazu prezen'et? = "Who did you gave your present to?"
 * Answer: Kudaze prezen cenu ega = "I gave the present to my wife"
 * ankodej: equivalent to where to. The answer uses the lative case.
 * Question: Ankodej egeg? = "Where are we going to?"
 * Answer: Egeg ana dom = "We are going home"
 * apkodej: equivalent to where from. The answer uses the ablative case.
 * Question: Apkodej Guillaume? = "Where is Guillaume from?"
 * Answer: Li Francihi = "He is from France"
 * apoká: equivalent to whose or from who. The answer uses the genitive case.
 * Question: Apoká bux gi? = "Whose is this book?"
 * Answer: Bux gi Antona = "This book is Anton's"
 * kalis: equivalent to how. The answer uses the instrumental case, unless they ask about an accompainment, in that case the comitative or the privative cases are used for affirmative or negative answers respectively.
 * Question: Kalis tu? = "How are you?"
 * Answer: Eg bilisikom = "I am fine" (lit. good)
 * ká: equivalent to who. The answer uses the accusative case.
 * Question: Ká lihi? = "Who are they?"
 * Answer: Lihi brotarar ega = "They are my brothers"
 * kis: equivalent to what or which. The answer uses the nominative case, unless they ask about an intention (or reason) or a topic, in those cases the causative or the temative cases are used respectively.
 * Question: Kis nomin'it? = "What is your name?"
 * Answer: Nomin ega Karolina = "My name is Karolina"
 * kodej: equivalent to where. The answer uses the locative case.
 * Question: Kodej tu? = "Where are you?"
 * Answer: Eg Amerike = "I am in America".
 * kota: equivalent to how much and how many. The answer uses the accusative case.
 * Question: Kota awto ej? = "How much is that car?"
 * Answer: Awto ej kwetarmil marg = "That car is four thousand marks"
 * óm: equivalent to when. The answer uses the temporary case.
 * Question: Óm intervú't verega? = "When is your job interview?"
 * Answer: Lunxose = "On Monday"

Prepositions
Prepositions in the Keltsvian language are a set of connecting words that serve to indicate a relationship between a content word (noun, verb, or adjective) and a following noun phrase (or noun, or pronoun), known as the object of the preposition. The relationship is typically spatial or temporal, but prepositions express other relationships as well. Keltsvian does not place these function words after their objects; the language does not use postpositions.
 * ana: equivalent to to. For lative case.
 * apo: equivalent to from. For ablative case.
 * do: equivalent to for. For causative case.
 * en: equivalent to in, at or on. For locative and temporary cases.
 * entir: equivalent to between. For locative case.
 * gag: equivalent to by. For instrumental case.
 * ki: equivalent to after. For temporary case.
 * kom: equivalent to with. For comitative and instrumental cases.
 * ku: equivalent to before. For temporary case.
 * lur: equivalent to the English language ´s. For genitive case.
 * ňew: equivalent to 'without. For privative case.
 * óki: equivalent to because. For causative case.
 * patir: equivalent to behind. For locative case.
 * per: equivalent to about. For temative case.
 * pitar: equivalent to in front of. For locative case.
 * teni: equivalent to until. For temporary case.
 * uči: equivalent to above. For locative case.
 * upo: equivalent to under. For locative case.
 * zi: equivalent to during. For temporary case.

Conjunctions
Keltsvian language has 6 different conjuntions, all of them have equivalents in English language:
 * ač: and.
 * he: no.
 * ita: so.
 * mo: but.
 * si: if.
 * we: or.

Dialectal variations
There are no dialectal variations in Keltsvian language due to the concentration of its speakers in a very concrete area of Eastern Europe. They are different accents from people who use it having another mother tongue, specially the Slavic language speaker communities within Keltsvia.

Verbs
Keltsvian verbs form one of the simplest areas of Keltsvian grammar. Keltsvian verbs undergo inflection according to the following categories: This language does not have phrasal verbs, irregular verbs, T-V distinction and grammatical voice and aspect.
 * Tense: past, present or future.
 * Number: singular or plural.
 * Person: first, second or third.
 * Mood: indicative, conditional or imperative.

Tense
Verbal tenses in Keltsvian work with prefixes added to the verb stem. There are 3 tenses: In Keltsvian there is also a gerund form, and it has the same use as the English -ing forms. They also use a prefix, in Keltsvian language it is knnown as a fake tense with the name of zóm or active tense and it uses the prefix zi-, this one can be combined with the real tenses. The following examples are made with the verb ejmoz (to go): It is possible to see that the beginning of the verb can modify the vowel of the prefixes due to the compliance of the orthography rules seen before.
 * Past (kwom): for any action happened in the past. They use the prefix: ku-.
 * Present (numkóm): for any action happening at the present time. They use no prefix.
 * Future (kóm): for any action that will take place in the future. They use the prefix ki-.
 * Past - ku + ejmoz: Tom kwejmozi = "Tom went"
 * Present - no prefix: Tom ejmozi = "Tom goes"
 * Future - ki + ejmoz: Tom kéjmozi = "Tom will go"
 * Gerund + past - zi + ku + ejmoz: Tom zikwejmozi = "Tom was going"
 * Gerund + present - zi + ejmoz: Tom zéjmozi = "Tom is going"
 * Gerund + future - zi + ki + ejmoz: Tom zikéjmozi = "Tom will be going"

Person and number
Keltsvian verbs are conjugated in three persons, each having a singular and a plural form. The conjugations are simple, because they just consist in the addition of a suffix. Because Keltsvian is a "pro-drop language", subject pronouns are often omitted.
 * 1st person singular: uses the suffix -e. Ex: Ejmoze - "I go"
 * 2nd person singular: uses the suffix -u. Ex: Ejmozu - "You go"
 * 3rd person singular: uses the suffix -i. Ex: Tom ejmozi - "Tom goes"
 * 1st person plural: uses the suffix -le. Ex: Ejmozle - "We go"
 * 2nd person plural: uses the suffix -lu. Ex: Ejmozlu - "You [all/guys] go"
 * 3rd person plural: uses the suffix -li. Ex: Ejmozli - "They go".

Mood
There are 3 grammatical moods in Keltsvian language:
 * Indicative (indikativ): used for factual statements and positive beliefs. When written they are recognised because of the ending -z of the verb, located just before the person and number suffix. Ex: Tom dumosozi cigaretu = "Tom smokes a cigarette".
 * Imperative (kasarativ): expresses direct commands, requests, and prohibitions. In this mood, the indicative marker is changed for the imperative marker -sz. Ex: He dumososzu = "Do not smoke"
 * Conditional (sitiv): used for conditional situations, it is an equivalent to would. In every example of this mood we can always find the conjuntion si (meaning "if"). Ex: Tom késmozi kolutak si he dumosozi = "Tom would be healthy if he would not smoke".

Verb esmoz
The Keltsvian verb esmoz (to be) is never used in the present tense. For example, to say "Theresa is beautiful" in Keltsvian you must say Theresa xajsok, literally meaning "Theresa beautiful".

Keltsvian verbs are sometimes taken from nouns, like pisgiz (to fish) which is taken from pisg (fish) or plusaz (to write) from plusa (feather), because people used to write with feathers in the past. Some verbs are derived from other verbs and they modify the meaning of the stem by the addition of prefixes. For example: Verbs are never derived from adjectives, with the only exception of colours, like the verb dubuz (to blacken), which is derived from dubu (black). Verb formation follows the nominal vowel harmony, taking the last vowel as reference and adding a -z at the end. Another example, we will take the word meaning red and we will form the verb to redden: dergos - dergosoz.
 * dus-: equivalent to mis-. Ex: stumuz becomes dustumuz, meaning to inform and to misinform.
 * en-: equivalent to trans-. Ex: magoz becomes enmagoz, meaning to form and to transform.
 * ko-: equivalent to co-. Ex: luruz becomes koluruz, meaning to own and to co-own.
 * kon-: equivalent to re-. Ex: plusaz becomes konplusaz, meaning to write and to rewrite.
 * kuki-: equivalent to inter-. Ex: agaz becomes kukágaz, meaning to act and to interact.
 * ni-: equivalent to de-, dis- and un-. Ex: faz becomes nifaz, meaning to do and to undo.
 * on-: equivalent to fore- and pre-. Ex: kupiz becomes onkupiz, meaning to order and to preorder.
 * uč-: equivalent to out- and over-. Ex: parnaz becomes učparnaz, meaning to sell and to oversell.
