Agreement: Subject–Verb, Adjective–Noun | Ukrainian Grammar

Agreement (узго́дження) is the machinery that makes Ukrainian words "match." It runs in two main circuits: subject–verb agreement and adjective–noun (more broadly, modifier–noun) agreement. The subject–verb circuit has a twist that surprises every English speaker — in the past tense, verbs agree by gender, not person — and the modifier–noun circuit puts a load on Ukrainian that English puts on nothing: a single noun phrase can have four or five words, each carrying a matching ending. This page consolidates both, with the cross-links you'll want for the deep dives.

💡

Two headlines to fix first: (1) present/future verbs agree by PERSON+number (я чита́ю, вони́ чита́ють), but past verbs agree by GENDER+number (він чита́в, вона́ чита́ла) — the past tense doesn't care who's speaking, only their gender. (2) Every word modifying a noun agrees in gender, number AND case simultaneously — adjectives, possessives, demonstratives all march in step.

Subject–verb agreement: present and future (person + number)

In the present and future, the verb's ending tells you the person and number of the subject — so reliably that the subject pronoun is often dropped (the ending already says who). This is the system laid out on the present-tense overview.

Person	Singular	Plural
1st	я чита́ю	ми чита́ємо
2nd	ти чита́єш	ви чита́єте
3rd	він/вона́ чита́є	вони́ чита́ють

Ми за́втра ї́демо до ба́бусі в село́.

We're going to grandma's in the village tomorrow. (ї́демо = 1st person plural, agreeing with ми.)

Чита́ю цю кни́жку вже ти́ждень.

I've been reading this book for a week now. (чита́ю = 1st person singular; я is dropped because the ending already says 'I'.)

Subject–verb agreement: PAST (gender + number, NOT person)

Here is the big surprise. The Ukrainian past tense descends from an old participle, so it agrees the way an adjective does — by gender and number, and it is blind to person. "I read" said by a man and "I read" said by a woman use different verb forms, even though both are "I."

Subject	Past form of чита́ти
він (he) / я (male speaker) / ти (male)	чита́в
вона́ (she) / я (female speaker) / ти (female)	чита́ла
воно́ (it)	чита́ло
вони́ (they) / ви	чита́ли

Я вже прочита́в цю кни́жку. (said by a man)

I've already read this book. (прочита́в = masculine — the speaker is male; person is irrelevant, only gender.)

Я вже прочита́ла цю кни́жку. (said by a woman)

I've already read this book. (прочита́ла = feminine — same 'I', different form, because the speaker is female.)

Вони́ вчо́ра поверну́лися з відпу́стки.

They came back from holiday yesterday. (поверну́лися = plural -ли, regardless of the genders involved.)

The full mechanics — including the -в that comes from an old -л, and the consonant-stem past — are on past-tense formation.

💡

When you learn a past-tense verb, you're really learning four forms at once: -в / -ла / -ло / -ли. Choose by the subject's gender and number, never its person. A woman saying "I did it" needs зроби́ла; a man needs зроби́в.

Adjective–noun agreement: gender + number + case, all at once

Anything that modifies a noun — an adjective, a possessive, a demonstrative — must match it in gender, number, AND case simultaneously. This is the heavy-lifting circuit. Watch one adjective, нови́й "new," reshape itself to its noun:

Noun phrase	Gender/Number	Meaning
нови́й стіл	masc. sg.	a new table
нова́ кни́га	fem. sg.	a new book
нове́ ві́кно	neut. sg.	a new window
нові́ книжки́	plural	new books
нови́х книжо́к	plural genitive	of new books

Ми купи́ли нови́й стіл і нову́ ша́фу.

We bought a new table and a new wardrobe. (нови́й agrees masc. with стіл; нову́ agrees fem.-acc. with ша́фу.)

У нові́й кварти́рі ще нема́є ме́блів.

There's still no furniture in the new flat. (нові́й = fem. locative, agreeing with кварти́рі after у.)

The dramatic case is the multi-word noun phrase, where every modifier carries a matching ending. English piles modifiers in front of a noun with no endings at all; Ukrainian makes them all inflect together:

Я познайо́мився з мої́м нови́м украї́нським дру́гом.

I got to know my new Ukrainian friend. (мої́м, нови́м, украї́нським — three modifiers, ALL instrumental masculine singular to match дру́гом after з.)

That single phrase has four words all carrying matching instrumental-masculine endings (-їм, -им, -им, -ом). This is the load English speakers most underestimate. The full declension patterns are on adjective agreement, deep dive and the adjectives overview.

Numeral agreement: a special, three-way system

Numbers agree with their nouns in a famously irregular way — the noun's form depends on which number: 1 takes the nominative singular, 2–4 take a special form (historically a dual), and 5+ take the genitive plural.

оди́н стіл, два столи́, п’ять столі́в

one table, two tables, five tables. (1 → nom. sg.; 2–4 → столи́; 5+ → genitive plural столі́в.)

У ме́не дві сестри́ і чоти́ри бра́ти.

I have two sisters and four brothers. (2–4 take the special form: дві сестри́, чоти́ри бра́ти.)

This system is large enough to have its own page — treat it as a separate skill.

Tricky agreement: politeness Ви, quantity words, хто

A few cases bend the basic rules:

Polite Ви takes a plural verb — even for one person. Addressing a single person formally, the verb and any past form go plural, exactly as English once used "you are" for one person.

Ви вже прийшли́, Іва́не Петро́вичу?

Have you arrived, Ivan Petrovych? (One person, formal Ви → plural verb прийшли́.)

Quantity-word subjects waver between singular-neuter and plural. A subject like бага́то люде́й "many people" or кі́лька студе́нтів "several students" can take either a singular neuter past verb (the grammatically strict choice) or a plural one (common, treating the people as individuals). Both are heard; the singular-neuter is the more formal/conservative.

На зу́стріч прийшло́ бага́то люде́й.

A lot of people came to the meeting. (прийшло́ = singular neuter, agreeing with the quantity word бага́то — the conservative choice.)

На зу́стріч прийшли́ бага́то люде́й.

A lot of people came to the meeting. (прийшли́ = plural, treating the people as individuals — also common.)

Хто takes a masculine singular verb, even when the real-world referent is female or plural. Хто is grammatically masculine singular.

Хто прийшо́в так пі́зно?

Who came so late? (прийшо́в = masculine singular by default, whoever хто turns out to be.)

Source-language comparison

For an English speaker, two facts have no English parallel. First, past-tense gender agreement: English "I read" never changes for the speaker's sex, but Ukrainian forces чита́в (male) vs чита́ла (female). You must internalise your own gender into your verbs. Second, the stacked modifier agreement: English "my new Ukrainian friend" has zero inflection; Ukrainian мої́м нови́м украї́нським дру́гом has four matched endings. The discipline is to set the noun's gender-number-case first, then make every modifier echo it.

For a Russian speaker, the whole agreement architecture is familiar — past by gender, modifiers by gender/number/case, polite вы plural, the 1/2–4/5+ numeral split — so the transfer is excellent. The differences are in the endings (e.g. masc. dative -ові, the vocative where applicable) rather than the system.

Common Mistakes

❌ Я прочита́в кни́жку. (said by a woman)

Wrong gender — the past agrees with the SPEAKER's gender, not the person: a woman says Я прочита́ла кни́жку.

✅ Я прочита́ла кни́жку. (woman speaking)

I read the book — feminine past -ла because the speaker is female.

❌ Ти прийшла́? (to a male friend)

Wrong gender — past agrees with the addressee's gender: to a man it's Ти прийшо́в?, to a woman Ти прийшла́?

✅ Ти прийшо́в? (to a man)

Have you come? — masculine -в for a male addressee.

❌ з мій нови́й украї́нський дру́гом

Modifiers don't agree — every word must be instrumental masculine to match дру́гом: з мої́м нови́м украї́нським дру́гом.

✅ з мої́м нови́м украї́нським дру́гом

with my new Ukrainian friend — all four words instrumental masculine.

❌ Ви прийшо́в? (formal, to one person)

Polite Ви takes a PLURAL verb, even for one person: Ви прийшли́?

✅ Ви прийшли́?

Have you arrived? — plural verb with formal Ви for a single addressee.

❌ два столі́в

Wrong numeral agreement — 2–4 take the special form, not the genitive plural: два столи́ (genitive plural столі́в is for 5+).

✅ два столи́, п’ять столі́в

two tables, five tables — 2–4 special form vs 5+ genitive plural.

Key Takeaways

Present/future verbs agree by PERSON + number (я чита́ю / вони́ чита́ють); the subject pronoun can be dropped.
Past verbs agree by GENDER + number, NOT person (він чита́в / вона́ чита́ла / воно́ чита́ло / вони́ чита́ли) — your own gender goes into your past-tense verbs.
Modifiers agree with their noun in gender + number + case all at once; a phrase like з мої́м нови́м украї́нським дру́гом carries four matched endings.
Numerals: 1 → nom. sg., 2–4 → special form, 5+ → genitive plural.
Special cases: polite Ви → plural verb (even for one person), quantity words waver singular-neuter/plural, хто → masculine singular.
