Appendix:Definite nouns

They are two forms to indicate that a noun is known (i.e. definite): by adding a definite article (te, ta, ti) or by inflecting the word.

Definite articles
The article must match the noun's gender. Te, ta, and ti correspond to masculine, feminine and neuter genders, respectively. See Appendix:Grammatical gender for further information.

Inflection
If the noun is plural, the singular form is inflected and then the -s suffix is added.
