Mocha grammar, step by step

Mocha is strictly Subject–Object–Verb. The verb is always the final element in a clause. Time expressions, objects, and postpositional phrases all come before the verb. This is one of the most consistent features of the language.

In Mocha, a full noun phrase acting as the grammatical subject takes the nominative/subject case suffix -i (or its allomorphs). Pronouns (like ane = I) often appear without the suffix, but full nouns are typically case-marked. This is a typical Omotic feature.

Every Mocha verb is built in three layers: the ROOT gives the basic meaning, the TAM (tense-aspect-mood) suffix marks when and how the action occurs, and the AGREEMENT suffix marks who is doing it. These three layers are always present, always in this order.

Mocha distinguishes masculine and feminine gender in nouns. The gender of the subject is reflected in the verb agreement suffix: 3SG.M and 3SG.F use different suffixes. Verbs must agree with their subject's gender.

Mocha uses postpositions — the relationship word comes AFTER the noun phrase. This is consistent with its SOV word order: everything modifying the verb phrase comes before the verb, and within those phrases, relationship words follow their nouns.

Mocha makes a fundamental distinction between imperfective (ongoing, habitual, or present action) and perfective (completed action). The TAM suffix changes: the imperfective uses no or minimal TAM morpheme; the perfective inserts a TAM suffix (like -t-) before the agreement suffix.

Mocha expresses negation by adding a negative suffix to the verb complex — after the TAM and agreement suffixes. This suffix-based negation is typical of Omotic languages and is the opposite of languages (like Arabic) that use a prefix or circumfix.

Mocha has a highly productive causative morpheme -iss- (or -is-) that inserts between the verb root and the TAM/agreement suffixes. It means "cause X to happen" or "make someone do X." This causative can be applied to almost any verb and is fundamental to the grammar.

Yes/no questions in Mocha are formed by intonation, or by a question particle at the end of the sentence. Information question words (who, what, where) appear in-situ — in the same position the answer would occupy, before the verb.

Mocha forms noun plurals primarily with a suffix. The exact plural suffix varies by noun class and gender, but the overall pattern is suffix-based. Masculine and feminine nouns may use different plural suffixes.

Mocha expresses possession by placing the possessor noun before the possessed noun, with the possessor in a genitive case form. No separate "of" word is needed — the case suffix on the possessor signals the relationship.

Mocha, like many SOV languages, allows the topic — the thing being talked about — to be fronted to the beginning of the sentence. The rest of the sentence follows normal order. This is a discourse-level strategy for emphasis and contrast.

Mocha relativizes by giving the relative verb a special participial or nominalized form — the verb takes a modifier form and directly precedes the head noun. There is no relative pronoun (no equivalent of "who" or "that"). The modified verb form signals "this verb describes the head noun."

Mocha uses a converb — a non-finite verb form — to chain sequential actions. The first action takes a converb suffix (a "then" form), and only the final verb is fully conjugated. This allows a series of actions to be expressed very efficiently.

Mocha grammar is strict SOV word order + three-layer verb morphology (root + TAM + agreement) + suffix-based negation + the productive causative -iss- — an Omotic system entirely different in structure from the Semitic and Cushitic languages spoken nearby.
