Jaxìka is a language based on several world languages. It takes grammatical features from a number of languages. There are two genders: masculine and feminine, three numbers: singular, dual and plural. The word order is always Subject-Object-Verb, though this is more of a guideline since the case system can allow for more freedom. 


There are four cases in jaxìka: nominative, genitive, accusative and dative. However, the nouns do not decline. Instead that is the work of the articles. The nouns only inflect to show number. There are three numbers: singular, dual and plural. Nouns are inseparable from their articles in jaxìka because without the article the case of the noun is unknown. The article must also always directly precede the noun, otherwise the case of the noun can be confused. 

The following noun declensions are shown with the definite article. The indefinite article is "o" for masculine nouns and "a" for feminine nouns. 

The declension of masculine nouns goes like so:

jebo (man)

case singular dual plural
nominative Ño jebo Ño jebü Ño jebu
genitive Ñoxi jebo Ñoxi jebü Ñoxi jebu
accusative Ñowa jebo Ñowa jebü Ñowa jebu
dative Ñosa jebo Ñosa jebü Ñosa jebu

Similarly for feminine nouns:

jeba (woman)

case singular dual plural
nominative Ña jeba Ña jebi Ña jebe
genitive Ñâxi jeba Ñâxi jebi Ñâxi jebe
accusative Ñâwa jeba Ñâwa jebi Ñâwa jebe
dative Ñâsa jeba Ñâsa jebi Ñâsa jebe

There are no irregular declensions or nouns that do not follow those rules in jaxìka. Pronouns are declined the same way as nouns except there is another declension for when the pronoun is the object of a preposition. The vowel endings are the same as nouns, so O, Ü and U denote masculine pronouns and A, I and E denote feminine pronouns. 

Person Nominative Accusative Genitive Dative Object of a Preposition
first (s.g.) ro, ra rowa, râwa roxi, râxi rosa, râsa roja, râja
first (dual) rü, ri rüwa, riwa rüxi, rixi rüsa, risa rüja, rija
first (pl.) ru, re ruwa, rewa ruxi, rexi rusa, resa ruja, reja
second (s.g.) to, ta towa, tâwa toxi, tâxi tosa, tâsa toja, tâja
second (dual) tü, ti tüwa, tiwa tüxi, tixi tüsa, tisa tüja, tija
second (pl.) tu, te tuwa, tewa tuxi, texi tusa, tesa tuja, teja
third (s.g.) no, na nowa, nâwa noxi, nâxi nosa, nâsa noja, nâja
third (dual) nü, ni nüwa, niwa nüxi, nixi nüsa, nisa nüja, nija
third (pl.) nu, ne nuwa, newa nuxi, nexi nusa, nesa nuja, neja


Verbs in jaxìka do not conjugate for person or for tense, only for affirmative or negative. Thus, the verb infinitive is the same as the affirmative form of the verb. Let's look at the verb saru (to speak) for an example. Saru would conjugate like this in the present tense. To save space the feminine forms of the pronouns are omitted from the table below. 

person affirmative negative
first (s.g.) ro saru ro sarune
first (dual) rü saru rü sarune
first (pl.) ru saru ru sarune
second (s.g.) to saru to sarune
second (dual) tü saru tü sarune
second (pl.) tu saru tu sarune
third (s.g.) no saru no sarune
third (dual) nü saru nü sarune
third (pl.) nu saru nu sarune


Tense is shown in jaxìka through particles and not morphemes attached to the verb. The two main tense particles are aja and maña. Aja is to denote the past tense and maña is to denote the future tense. These tense particles can appear anywhere in a sentence and function kind of like adverbs. The only place you cannot place these particles is between an article and a noun. This is so the case of the noun is not confused. 

Some examples showing the correct placement of particles. 

Aja to rosa ñâwa jaxìka saru = You spoke jaxìka to me. 

To aja rosa ñâwa jaxìka saru = You spoke jaxìka to me.

To rosa aja ñâwa jaxìka saru = You spoke jaxìka to me.

To rosa ñâwa jaxìka aja saru = You spoke jaxìka to me.

To rosa ñâwa jaxìka saru aja = You spoke jaxìka to me. 

As you can see, the sentence in English can only be written one way, but it can be written several ways in jaxìka.
