Ukrainian grammar, step by step

The verb ending tells you who is doing the action. Each person has its own ending, so the subject pronoun can often be dropped.

The default word order is subject-verb-object, but because case endings mark grammatical roles, words can be rearranged to shift emphasis without changing meaning.

Every noun belongs to one of three genders — masculine, feminine, or neuter — identifiable by its ending. There are no articles like "the" or "a."

The direct object takes the accusative case. For masculine animate nouns, the accusative looks like the genitive; for inanimate masculine and neuter nouns, it stays the same as nominative.

Nouns change their endings to form plurals. Masculine and feminine nouns typically add -и or -і, while neuter nouns often end in -а or -я.

The past tense is formed by replacing the infinitive ending with -в (masculine), -ла (feminine), -ло (neuter), or -ли (plural). It agrees with the subject's gender, not person.

Place "не" directly before the verb to negate it. Negative words like "ніхто" (nobody) and "нічого" (nothing) require "не" as well — double negation is mandatory.

Yes/no questions use rising intonation alone, or add the particle "чи" at the start. Information questions begin with a question word like "хто" (who), "що" (what), or "де" (where).

The genitive marks possession ("of"), absence ("there is no"), and quantity. Masculine nouns add -а or -у, feminine nouns change -а to -и, and plurals often lose their ending.

Adjectives must match their noun in gender, number, and case. The ending changes for each combination.

Every verb exists in two aspects. The imperfective describes an ongoing or repeated action; the perfective marks a completed, single action. Perfective verbs are usually formed by adding a prefix.

Adding -ся (after a consonant) or -сь (after a vowel) makes a verb reflexive. It can mean the action reflects back on the subject, is reciprocal, or forms a passive.

Perfective verbs conjugated in the present tense express a future action. For imperfective verbs, use "буду/будеш/буде..." plus the infinitive.

The dative marks the recipient or beneficiary. It is also used in impersonal constructions expressing feelings or states, where the experiencer appears in the dative.

The instrumental marks the tool or means ("with a pen"), a companion ("with someone"), and the predicate noun after "бути" (to be) in formal or past/future contexts.

When calling someone by name or title, the noun takes a special vocative form. This case is alive and widely used in everyday Ukrainian.

Ukrainian grammar is a system of interlocking agreements — case, gender, aspect, and the vocative all interact. Once you can follow how a noun's case ripples through the adjectives around it, and how aspect reshapes the timeline of an event, you have the skeleton of the language.
