Oromo grammar, step by step

The verb always comes at the very end of the sentence. The subject opens, the object sits in the middle, and everything builds toward the final verb.

The verb ending changes to match the subject's person, number, and — in the third person singular — gender. Masculine and feminine subjects require different endings.

Every noun belongs to one of two genders — masculine or feminine. The gender affects which verb ending is used for third-person subjects and which form adjectives and determiners take.

In Oromo, the subject of the sentence receives a special nominative suffix (-ni or -n) — the object, by contrast, appears in its plain unmarked form. This is the opposite of what many languages do, where objects get a special marker.

The absolutive is the unmarked, base form of the noun — it is used for direct objects, citation, and predicate nouns. It contrasts with the marked nominative used for subjects.

The past tense (perfective) describes completed actions. It uses a different set of person endings than the present — compare present "dubbadha" (I speak) with past "dubbadhe" (I spoke).

The present tense describes habitual or ongoing actions. The verb endings for each person are slightly different from the past tense, creating a clear contrast between completed and ongoing events.

Negation uses the particle "hin" before the verb, and the verb takes a special negative ending different from the affirmative. Both the particle and the changed ending work together.

Information questions use words like "maal" (what), "eenyu" (who), "eessa" (where), "yoom" (when), and "akkam" (how). Yes/no questions can use lengthened final vowels or rising intonation.

The genitive marks possession. It is formed by lengthening the final vowel of the noun or using a specific suffix. Possessive pronouns like "koo" (my), "kee" (your), and "isaa" (his) follow the noun they modify.

Beyond nominative and genitive, Oromo has a dative (to/for), instrumental (with/by means of), ablative (from), and locative (at/in) case, each marked by its own suffix on the noun.

Adding -s- or -sis- to the verb root creates a causative meaning — "make/cause someone to do the action." This single suffix turns "learn" into "teach" and "eat" into "feed."

The passive voice adds -am- to the verb stem, indicating that the subject receives the action rather than performing it. Oromo also has a middle voice (-adh-/-at-) for actions affecting the subject.

Clitic particles like "-tu" or "-tuu" can attach to any noun phrase to mark it as the information focus — the most important or new piece of information in the sentence.

Converbs chain multiple actions together without needing conjunctions like "and." Each non-final verb takes a converb form (often with a lengthened final vowel -ee), and only the last verb carries tense and person marking.

Oromo grammar is built from layered patterns: SOV order, marked nominative, gender, person suffixes on verbs, causative and passive derivations, case suffixes, focus clitics, and converbs. Once you recognize the layers, even complex sentences reveal their structure piece by piece.
