The Present of Бути (and the Missing Copula)

Ukrainian has a verb "to be" — бу́ти — but in the present tense it almost always vanishes. "He is a student" is simply Він студе́нт, with no word for "is." This is one of the first things that feels strange to an English speaker, and one of the most reliable beginner errors is to put a "to be" word back in where Ukrainian wants nothing. There is a present form, є, but it earns its keep in only a few specific jobs — existence, possession, emphasis — and the rest of the time you leave a clean, copula-free sentence. This page teaches both halves: when to drop the verb entirely, and when є (and its negative нема́є) must appear.

The zero copula: the normal present

In a plain present-tense sentence that links a subject to a noun, adjective, or place — "X is Y" — Ukrainian uses no verb at all. The subject and predicate simply sit next to each other.

In writing, when both the subject and the predicate are nouns, a dash often stands in for the missing verb — especially in definitions, headlines, and emphatic equations. You read the dash as a silent "is."

The form є: one word for all persons

бу́ти does have a present form: є. Historically є was the 3rd-person singular ("is"), and old grammars list a fuller athematic paradigm, but modern standard Ukrainian uses є invariantly — the same є for I am, you are, he is, we are, they are. You will not need a different word for each person.

The trick is not the form — there is only one — but knowing when є is required and when it is wrong. There are three clear jobs.

Job 1 — existence and possession (у + genitive + є)

This is the most important use, and the one beginners under-use. To say someone has something, Ukrainian most often does not use a "have" verb at all. It says, literally, "at someone there is something":

У + (person in the genitive) + є + (thing in the nominative)

Here є means "there is / exists," and dropping it would be wrong — this is the mirror-image error to over-using є. The same є covers pure existence ("there is X"), not just possession:

The possessive pattern with є, and how it competes with the verb ма́ти "to have," is treated in full on мати vs у мене є and existential and possessive sentences.

Job 2 — the negative: нема́є + genitive

To negate existence or possession, є does not just take ні in front of it. It is replaced by a special negative word, нема́є (often shortened to нема́ in speech), and — crucially — the thing that does not exist goes into the genitive case, not the nominative.

У + (person, genitive) + нема́є + (thing, GENITIVE)

Compare the pair directly: in the positive, the possessed noun is nominative (час); in the negative, it becomes genitive (ча́су).

This is the genitive of negation, one of the deepest case rules in Ukrainian, and it is so consistent that нема́є can be treated as a fixed unit that always grabs the genitive. See the genitive of negation for the whole system.

Job 3 — emphasis, formal definitions, and the instrumental

In neutral speech you drop the copula, but in formal, emphatic, or definitional statements є comes back — to assert that something truly is the case, or in the elevated register of constitutions, contracts, and academic prose. In this use, the predicate noun frequently goes into the instrumental case (держа́вою), not the nominative — a formal pattern you should recognise even before you produce it.

In ordinary conversation, all three of those would normally be said without є (Украї́на — незале́жна держа́ва; Я громадяни́н Украї́ни). The є adds weight, formality, or the flavour of a written definition. The choice between a nominative and an instrumental predicate is taken up on predicate nominative vs instrumental.

Past and future fill the gap

It is worth noting why the present feels so empty: бу́ти has perfectly ordinary forms in the past and future, and they are not dropped. The copula only disappears in the present.

So the "missing" copula is a present-tense quirk specifically: the moment you move off the present, був / була́ / було́ / були́ and бу́ду / бу́деш / бу́де… reappear and behave like any other verb. The future forms of бу́ти also double as the auxiliary of the analytic future (бу́ду чита́ти).

Source-language comparison

For an English speaker, the hard part is resisting the urge to translate "is/am/are." English cannot make a sentence without a verb, so "He student" feels broken — but in Ukrainian Він студе́нт is complete and correct, and inserting є there (Він є студе́нт) sounds stilted or foreign. Train two reflexes: (1) for "X is Y," say it with *no verb; (2) for "I have / there is," reach for у + genitive + є, and negate it with нема́є + genitive. Those two reflexes cover the vast majority of present-tense "to be."

For a Russian speaker, the zero copula is familiar (Russian also drops быть in the present), but two Ukrainian specifics differ: the possessive idiom uses є overtly far more readily than Russian's bare "у меня машина," and the negative is the single word нема́є / нема́ (+ genitive), where Russian uses "нет." Use є and нема́є, not Russian patterns.

Common Mistakes

Key Takeaways

• The present of бу́ти is normally dropped: Він студе́нт, Я вдо́ма, Вона́ ро́зумна — no word for is/am/are.
• Between two nouns, a dash stands in for the verb: Київ — столи́ця Украї́ни.
• The present form є exists for all persons (one word) but is used sparingly — for existence/possession (У ме́не є…), emphasis, and formal definitions (often + instrumental: є держа́вою).
• "Have" = у + genitive + є + nominative: У ме́не є час.
• The negative is нема́є / нема́ + genitive: У ме́не нема́є ча́су — never не є, and never a nominative after нема́є.
• Two opposite errors to avoid: inserting є in plain sentences, and forgetting є (and нема́є) in possession.
