Geyson

Classification and Dialects
Geyson is broadly an agglutinative language with grammatical markings for both nouns and verbs. Geyson is also an active-stative language meaning the subject of an intransitive verb may be marked like either the agent of a transitive verb (the active case) or the patient of an intransitive verb (the stative case). The case of the intransitive subject depends on the volition of the subject where the active case indicates a higher level of volition and the stative case indicates a lower level of volition.

Here, the first sentence implies that the dog is being forced to eat - being fed - while the second implies the dog is eating of its own volition - a more accurate translation of the sense of eating.

meyng (dog root) → kemeyng soimon (stative.dog eats) vs. xtameyng soimon (active.dog eats)

Vowels
Geyson has three basic vowel qualities: ⟨e⟩ (mid-front), ⟨o⟩ (mid-back) and ⟨a⟩ (low-back). The vowel ⟨e⟩ varies between [e] and [i~ɨ] depending on its environment. Each vowel may occur either short or long, and oral or nasalized, giving a total of 12 combinations. Vowels can also be pronounced with high or low pitch, i.e. Geyson has two tones. Length, pitch and nasalization are phonemic.

Tones
The two tones of Geyson are high and low. Orthographically, high tone of a short vowel is indicated by an ⟨i⟩ following the affected vowel - ⟨ai⟩, while low tone is left unmarked - ⟨a⟩. The high tone of a long vowel is indicated by a ⟨y⟩ following the affected vowel - ⟨ay⟩, again the low tone is left unmarked - ⟨a⟩. This reflects the tonal polarity of Geyson in which syllables have a low tone by default.

Long vowels normally have level tones ⟨ay, aa⟩, however, in grammatical contractions and in loan-words such as ⟨keiendo⟩ ('wine' from {regional language} ⟨kinjddu⟩), long vowels may have falling ⟨aia⟩ or rising ⟨aai⟩ tones.

The sonorants /n/ and /m/ also carry tone when they are syllabic. Here, the high tone is marked with a ⟨y⟩ - ⟨ny, my⟩ -while the low tone is left unmarked ⟨n, m⟩.

Even though low tone is the default, these syllables are not underspecified for tone: they have a distinct phonetic tone, and their pitch is not merely a function of their environment. As in many languages, the pitches at the beginnings of Geyson vowels are lower after voiced consonants than after tenuis and aspirated consonants. However, the type of consonant has little effect on the pitch in the middle of the vowel, so that vowels have characteristic rising pitches after voiced consonants. After ejective consonants, only high tones are lowered, so that the distinction between high and low tone is reduced. The pitch of a vowel is also affected by the tone of the previous syllable. In most cases, this has as great of an effect on the tone of the other syllable as its own tone.

Nouns
Nouns can take affixes of possession, reflexive relation, honorifics, class/gender and case.

Compounds can be formed in three ways:
 * nominal root+nominal root:
 * ge-naan "summit" (head-hill)
 * verbal root+nominal root:
 * khain-on'n-te "inferno" (to burn-bone)
 * attributive root/particle+nominal root:
 * nein-tsee "dwarf" (small-man)

Gender
There are 12 genders within which all nouns fall in Geyson. These genders do not represent physical gender (as in male and female) but rather represent the type, function, size, animacy etc. of a noun. These classifications may also be considered noun class.

These genders each carry unique grammatical marking and are usually classified with the following titles:
 * 1) Person - kinship terms, job titles, some body parts
 * 2) Animal/Tree - most animals, large plants
 * 3) Moving Object - water, celestial bodies, tools
 * 4) Stationary Object Large - land features, immovable objects
 * 5) Stationary Objects Small - low animacy small objects
 * 6) Foodstuffs - prepared food, small plants
 * 7) Neuter 1 - miscellaneous items, loan words
 * 8) Neuter 2 - miscellaneous items, loan words
 * 9) Big Concepts - concepts
 * 10) Place Specific - names of locations
 * 11) Place General - types of places
 * 12) Place Internal - emotions, thoughts

Case
Each grammatical gender is marked with a prefix which changes according to case. There are 6 cases in Geyson (Ergative, Absolutive, Locative, Benefactive, and Instrumentive). Originally classes and cases had separate prefixes marked class.case.root. Although these prefixes are retained as separate characters in writing, they are pronounced as the outlined contractions in all circumstances, which are reflected in the romanization. The original case prefixes can be seen in parenthesis on the top row of the chart below.

Posession
Possessive prefixes mark for the possessed case (although it functions differently from other cases) and change according to class and possessor. Possessed case can mark a noun without reference to any possessor using the indefinite form, or to a specific possessor using the other forms, this is equivalent to using possessive pronouns (e.g. my, your, his, her etc.). The possessor is indicated by proximity to the noun in the possessed case, with the usual structure being possessed followed by possessor (similar to the genitive construction ____ of ____). To determine the function of the possessed noun in the sentence, the possessor is marked with its case.
 * haitso "poem (root)" → s.haitso ta.deyso kate "the man writes a poem; lit. the man’s poem is written"

The indefinite possessor functions as a sort of ‘dummy’ possessor and is attached as a suffix. The appropriate class/case prefix must also added to indicate the function of the noun.
 * ta.khoyb.ol koi dnainde "one’s hands touch me"

Some nouns, such as words for body parts and kinship terms, must always be possessed. They cannot be used without a possessive prefix, or otherwise must be used with an absolute suffix to express an indefinite possessor. In a conversation, after the possessor is established through the first construction or context, the indefinite possessor construction is also frequently utilized. The possessive prefixes are as follows and precede all class marking. The prefix listed first is used before a root starting with a vowel, the prefix listed second is used before a root starting with a consonant.
 * k.ok "my room"


 * x.taa "my name"

The absolute suffix is usually el but can also have the form al, or ol: khoyb-ol "hand (of some unspecified person)” Because the absolute suffix is neither singular nor plural, it takes the singular posessor form of the plural noun. This however in simply a formality because -s assimilates with the -Vl characteristic to the absolute suffix

Number
Nouns in Geeso can be either singular or plural (mass nouns are grammatically singular).

The plural suffixes for a noun change based on whether or not the noun is possessed: Several nouns take on irregular plural forms the most common of which are:
 * ‘-s’ is the plural suffix for possessed nouns, linked with possessive prefixes:
 * a-retsaa-s "your teeth"
 * k-eynha-s "my fingernails"
 * ‘-ta’ is the plural suffix for non-possessed nouns:
 * de.xoo.ta "hills"
 * ke.mot.ta "birds"
 * ‘-ka’ is the plural suffix for objects that come in pairs, or when it is necessary to indicate the plural of both the noun and the possessor:
 * sa-dzekeen'n-ka "my (two) ears"
 * sa-been-ka "their names"

Honorifics
When talking about someone of superior status, the speaker must use special nouns. Generally, someone is superior in status if he or she is an older relative, a stranger of roughly equal or greater age, an employer, a teacher, a customer, or the like. Someone is equal or inferior in status if he or she is a younger stranger, a student, an employee or the like.

One way to accomplish this is by using ‘honorific’ nouns in place of regular ones.

aphoy (food inf.) → adeindo (food f.)

The honorific suffix -nei is affixed to many kinship terms to make them honorific.

moyra (grandmother inf.) → moynei (grandmother f.)

One may use the informal terms to refer to members of one’s own family while using the honorific terms to refer to members of other families affectionately.

Verbs
There are two types of verb roots: consonant roots and vowel roots. Consonant roots end in a nasal, stop or fricative and vowels roots end in vowels. soim is a consonant root meaning“eat” and dai is a vowel root meaning “have”.

Consonant Roots
Consonant roots have 6 open forms as well as the closed -de, -da, and -do forms which are each used for different grammatical functions and constructions. * vowel ending are pronounced nasally after nasal consonants

** ‘de’ and ‘da’ endings assimilate to the place of articulation of nasal consonant stems and the plosive blocks the transfer of tone

Notes on stem form uses:

Base 1 - negative form / with -n becomes negative present tense

Base 2 - infinitive form / can be combined with other verbs and used with the honorific endings (both positive and negative)

Base 3 - dictionary form / used in dictionaries and the regular present tense

Base 4 - imperative and conditional form / used plain it is an offensive command and with -ga is used as an if verb (e.g. sómą́ą́ga - If he’d just eat it)

Base 5 - volitional form / used plain means “let’s ___” (e.g. soimoon! - let’s eat!), the honorific form can also take on the -oo ending to become volitional

Base 6 - interrogative form / used to form questions, the honorific form can also take on the -ee ending to become interrogative, becomes negative with -n

“De” Form - progressive form / used for ongoing actions

“Da” Form - preterite form / used for completed actions

“Do” Form - habitual form / used for habitual actions

Vowel Roots
Vowel roots have three forms which are used for grammatical functions. These are the same as the closed forms for the consonant roots and take the suffixes -de, -da and -do.

Honorifics
All verbs and adjectives can be converted into an honorific form using the suffix -se. Specifics regarding this can be seen in the section on verb conjugation. A few verbs, however, similar to nouns, have a suppletive form which should be used in place of the regular verb to convey honorifics. These verbs are conjugated as normal verbs although they never take on the honorific suffix.

soim (eat inf.) → doinse (eat f.)
