Quantity Adverbs (Багато, Мало, Скільки, Стільки)

In English, "many" and "much" just sit in front of a noun and nothing else changes: many friends, much time. Ukrainian quantity words — бага́то "a lot," ма́ло "little," трохи "a bit," скі́льки "how much," сті́льки "so much" — do something English never asks of its quantifiers: they force the counted noun into the genitive case, and they often make the verb behave as if the subject were a neuter singular. Get this pattern into your bones early, because it returns the moment you start counting with numbers.

The core rule: quantity word + genitive

These words are grammatically adverbs (indeclinable — they never change form), but each one demands that its noun appear in the genitive. Think of the quantity word as a magnet that pulls the following noun into the genitive.

The genitive comes in two flavours depending on whether you can count the noun:

• Mass / uncountable nouns → genitive singular: бага́то робо́ти "a lot of work," трохи води́ "a bit of water," ма́ло ча́су "little time."
• Countable nouns → genitive plural: бага́то друзі́в "many friends," ма́ло люде́й "few people," скі́льки книжо́к "how many books."

Скі́льки and сті́льки — the question-and-answer pair

Скі́льки ("how much / how many") is your everyday question word for quantity and price, and it takes the genitive just like the rest. Сті́льки ("so much / so many," "this many") is its mirror-image answer.

The two often pair up in a "as many… as…" frame: скі́льки treba, сті́льки і ві́зьмеш "you'll take as much as you need."

Verb agreement: the neuter-singular trick

Here is the part that surprises English speakers. When a phrase like бага́то люде́й is the subject, the verb does not go plural by default. In the past tense it usually stands in the neuter singular, as if the subject were "an amount":

That прийшло́ is neuter singular, not plural прийшли́. The logic: the grammatical subject is really the quantity ("a-lot-of-people came"), and a quantity is treated as a single neuter mass. This is the same agreement you'll meet with the numbers 5 and up (п’ять студе́нтів прийшло́).

A plural verb (прийшли́) is also heard and increasingly common in speech, especially when the people are seen as distinct, active individuals. Both are acceptable; the neuter singular is the more conservative, "textbook-correct" choice and the one to default to in writing.

How this differs from English (and a note on numbers)

English quantifiers are case-neutral: the noun after many/much/few/a lot of is in its plain dictionary plural or singular. Ukrainian instead routes everything through the genitive, and it splits mass from count by choosing genitive singular versus genitive plural. So the English contrast "much money / many coins" is matched in Ukrainian by the same quantity strategy but different genitive numbers: бага́то гро́шей (gen pl — гро́ші is plural-only) versus бага́то молока́ (gen sg, a mass noun).

This is not an isolated quirk. The numbers п’ять and above behave identically — п’ять кни́жок "five books" is п’ять + genitive plural, exactly like бага́то кни́жок. So mastering quantity adverbs is a free down-payment on numeral agreement; see genitive with quantifiers and numeral agreement.

One more contrast: трохи ("a little / a bit") is invariable and always takes the genitive, where English has two different words — a little water (mass) versus a few nuts (count). Ukrainian uses трохи for both and lets the genitive number do the distinguishing: трохи води́ (gen sg) versus трохи горі́хів (gen pl).

Common Mistakes

Key Takeaways

• Quantity adverbs (бага́то, ма́ло, трохи, чима́ло, до́сить, скі́льки, сті́льки…) are indeclinable but govern the genitive.
• Mass nouns → genitive singular (бага́то ча́су); count nouns → genitive plural (бага́то друзі́в).
• A quantity-phrase subject takes a neuter-singular verb in careful Ukrainian (прийшло́ бага́то люде́й), though plural agreement is spreading in speech.
• Скі́льки? asks quantity and price; сті́льки answers "this/so much."
• These are the same agreement rules you'll meet with numbers 5+ — learn them once, use them twice.
