Becoming: Ставати/Стати and the Instrumental

To say someone becomes something in Ukrainian, you reach for the aspect pair става́ти / ста́ти "to become" — and you put the thing they become into the instrumental case. Він став *лі́карем "he became a doctor"; Я хо́чу ста́ти програмі́стом* "I want to become a programmer." This instrumental-after-"become" is one of the most reliable error spots for English speakers, who naturally leave the predicate in the dictionary (nominative) form. The same verb also has a second life as an impersonal of changing weather and mood — Ста́ло те́мно "it got dark" — where the predicate is an adverb, not a noun. This page handles both, plus the small family of change-of-state verbs (залиша́тися "remain," виявля́тися "turn out") that share the instrumental rule.

става́ти / ста́ти — "become" + the instrumental predicate

The pair splits the usual way:

• става́ти (imperfective) — the process, repeated or ongoing becoming ("is becoming," "keeps becoming");
• ста́ти (perfective) — a single completed transition ("became").

They conjugate quite differently, so learn both. The imperfective става́ти has the present-tense forms стаю́, стає́ш, стає́, стаємо́, стаєте́, стаю́ть. The perfective ста́ти has the simple future (= present-form, "will become") ста́ну, ста́неш, ста́не, ста́немо, ста́нете, ста́нуть.

The past is the regular gendered set off the ста́- stem: став (m.), ста́ла (f.), ста́ло (n.), ста́ли (pl.) for the perfective, and става́в / става́ла / става́ло / става́ли for the imperfective.

Note that any adjective in the predicate goes into the instrumental too, and agrees with the noun: став відо́мим лі́карем, ста́ла впе́внішою. The whole noun phrase shifts case together. The deeper logic of why "become" takes the instrumental — the case marks a temporary or acquired role, a state you move into — is laid out on the predicate nominative vs instrumental page.

The impersonal: ста́ло + adverb — "it got / it became ADJ"

The verb has a second, very common use that looks completely different. To say the weather, the light, or a mood changed — "it got cold," "it got dark," "things got better" — Ukrainian uses an impersonal construction: the neuter form ста́ло (or present стає́) with no subject at all, followed by a predicative adverb (-о form), not a noun.

• Стає́ те́мно — "it's getting dark"
• Ста́ло хо́лодно — "it got cold"
• Ста́ло кра́ще — "things got better / it got better"

The person affected, if any, appears in the dative — Мені́ ста́ло ле́гше "I felt better / it became easier for me." This is the same dative-experiencer machinery you meet across Ukrainian impersonal sentences.

So the same verb drives two patterns: a personal one with an instrumental noun (Він став лі́карем) and an impersonal one with an adverb (Ста́ло те́мно). Tell them apart by what fills the predicate slot: a noun/adjective → instrumental; an adverb (-о) → impersonal, no subject.

ста́ти + infinitive — "to start / take to doing"

A third, idiomatic use: ста́ти + infinitive can mean "to begin, to take to" doing something — a slightly more literary alternative to почина́ти. Він став чита́ти "he began to read / he took to reading." It is common in narrative.

The instrumental family: залиша́тися, виявля́тися, роби́тися

Several other change-of-state and copula-like verbs share the instrumental-predicate rule. Learn them together — once the instrumental clicks for ста́ти, it clicks for all of these:

• залиша́тися / залиши́тися "to remain, stay (being)" — Він залиши́вся *дру́гом* "he remained a friend."
• виявля́тися / ви́явитися "to turn out (to be)" — Це ви́явилося *обма́ном* "it turned out to be a deception."
• роби́тися / зроби́тися "to become, get" (more colloquial than става́ти; also takes an adverb impersonally) — Зроби́лося *те́пло*.
• вважа́тися "to be considered" — Він вважа́ється *експе́ртом*.

Quick reference

Source-language comparison

For an English speaker, English "become" is followed by a bare noun — "became a doctor" — with no case marking at all, so there is simply no signal telling you to inflect. Ukrainian demands the instrumental: став *лі́карем, not став лі́кар*. The good news is that this is the same rule you already learned for бути in the past and future (був студе́нтом, бу́де вчи́телем — see бути conjugation). "Become" is just another verb in that instrumental-predicate club. The other half — "it got dark / cold" — has no "it" in Ukrainian at all: not воно́ ста́ло те́мно, but the subjectless Ста́ло те́мно. English's dummy "it" is dropped entirely. For the case forms themselves, see instrumental forms.

For a Russian speaker, the construction is identical in shape (стать + instrumental, стало темно), so the framework transfers directly; the work is the Ukrainian forms — стаю́ / стає́ш (not станови́тися in the everyday sense), ста́ну / ста́неш, and the spelling/stress of виявля́тися, залиша́тися.

Common Mistakes

Key Takeaways

• става́ти / ста́ти = "become"; the predicate noun and any adjective go in the INSTRUMENTAL — став лі́карем, ста́ла відо́мою.
• Conjugation: imperfective стаю́ / стає́ш / стає́…; perfective future ста́ну / ста́неш / ста́не…; past став / ста́ла / ста́ло / ста́ли.
• The impersonal ста́ло / стає́ + adverb (-о) means "it got ADJ" — Ста́ло те́мно, with no subject; the affected person is dative (мені́ ста́ло кра́ще).
• ста́ти + infinitive = "to start / take to doing" (став чита́ти).
• The instrumental rule extends to залиша́тися "remain," виявля́тися "turn out (to be)," роби́тися "get/become," вважа́тися "be considered."
• This is the same instrumental бути takes in past/future — "become" simply joins that club.
