Langi

Nouns
In Langi, there are five cases. They are Abjective, Dative, Genative, Prepositional and Essive. There are also three numbers, Singular, Dual and Plural.

Abjective
The Abjective case is the most important. Its nouns end in the suffix -i. Abjective case nouns are used as the subjects and objects of a sentence. For example, in "The cat sees a dog" "cat" is the subject and "dog" is the object. In Langi, the sentence is "Ciba gati vido perosi." The bolded nouns are in the abjective case.

Dative
Dative case nouns end in the suffix -ir. Dative case nouns are used as the indirect objects of a sentence. For example, in "Mary reads the kindergarteners a story" "kindergarteners" is the indirect object. In Langi, the sentence is "Mari ŝi rando cibiro kindiro libransi." The bolded nouns are in the dative case.

Genative
Genative case nouns end in the suffix -u. Genative case nouns are possessives. For example, in "my friend's book" "my" and "friend's" are possessives. In Langi, the phrase is "mu amigu libransi" The bolded nouns are in the genative case.

Prepositional
Prepositional case nouns end in the suffix -as. Prepositional case nouns are the objects of prepositions. For example, in "through the woods" "woods" is the object of "through." In Langi, the phrase is "θaraθ cä muras" The bolded nouns are in the prepositional case.

Essive
Essive case nouns end in the suffix -ä. Essive case nouns in English mean like/as something. For example, in "He dressed like a girl." "girl" is in the essive case. In Langi, the sentence is "Hi famä θeson." The bolded nouns are in the essive case.

Numbers
Dual is two related items, to form it, add -a. Plural is two unrelated or three or more of anything. To form it, add -o.

Verbs
In Langi, verbs are conjugated by tense and aspect. The four tenses are Past, Present, Future and Future-in-Past. The last one in for things that used to be in the future. The two aspects are perfect and imperfect. Perfect is "he HAS done something" imperfect is not.
