Numbers

After this page you will be able to count in Ukrainian and put the noun after a number in the right form: оди́н до́лар, два до́лари, п’ять до́ларів. You will know which numbers change for gender, how оди́н, два, три, чоти́ри and п’ять change for case, and how to say prices and ages.

You have met the basic rule on the shopping page and on the genitive page. This page brings it together and goes a step further. Numbers that say how many are cardinal numbers (кі́лькісні числі́вники). Numbers that give a position, such as first and second, are ordinal numbers; they have their own page.

Counting from 1 to 1,000

Larger numbers are built as in English, one word after another: два́дцять оди́н (21), сто п’ятдеся́т чоти́ри (154) [src: ukma-ukrainian-foreign-language, Lesson 8]. The parts are written as separate words: ти́сяча п’ятсо́т, три́дцять ві́сім. Numbers such as одина́дцять, п’ятдеся́т and три́ста are one word [src: pravopys-2026, §38].

Ти́сяча (thousand), мільйо́н (million) and мілья́рд (billion) behave like nouns and change their endings like other nouns [src: pravopys-2026, §105; ukma-ukrainian-foreign-language, Lesson 8]. So they follow the rule for nouns after numbers, below: дві ти́сячі, п’ять ти́сяч.

One and two change for gender

Only one and two (and півтора́ / півтори́, below) have different forms for the gender of the noun [src: ukma-ukrainian-foreign-language, Lesson 8; pravopys-2026, §105]:

• Оди́н, одна́, одне́ agree like an adjective. The neuter also has the less common form одно́ [src: pravopys-2026, §105].
• Два goes with masculine and neuter nouns, дві with feminine nouns.
• Три, чоти́ри and all the other numbers have one form for every gender.

The noun after a number

The form of the noun depends on the last word of the number [src: ukma-ukrainian-foreign-language, Lesson 8]:

• After 1: the nominative singular.
• After 2, 3, 4: the nominative plural.
• After 5 and above, including 11 to 14: the genitive plural.

So the deciding word is the last one you say. Со́рок три гри́вні (43) ends in three, so it takes the nominative plural. П’ятна́дцять гри́вень (15) is one word, and it is not 2, 3 or 4, so it takes the genitive plural [src: ukma-ukrainian-foreign-language, Lesson 8].

Masculine nouns after два, три and чоти́ри take the plural endings -и or -і: два хло́пці, три робітники́, чоти́ри слухачі́ [src: pravopys-2026, §88, note 1]. The noun plurals page shows how these plurals are formed, and the genitive page shows the genitive plural.

Thousands and millions

Ти́сяча is a feminine noun in -а, so it takes дві and changes like other feminine nouns in -а. Мільйо́н is masculine. The thing you count then goes into the genitive plural, after the word for thousand or million.

Numbers in other cases

The rule above is for the nominative, and for the accusative of things. A number can also stand in another case, for example after a preposition. Then the number changes its form too. Learners mostly need the forms below; the orthography gives the full tables [src: pravopys-2026, §105].

Один

Оди́н changes like an adjective and agrees with its noun in gender and case.

These are the forms and stresses of the orthography’s table [src: pravopys-2026, §105]. The accusative masculine is одного́ with people and animals, and оди́н with things, as for adjectives. The orthography also lists less common feminine forms such as одно́ї. In phrases like one another (оди́н до одного, оди́н одному), the orthography puts the stress on the first syllable [src: pravopys-2026, §105, note]. The dictionary gives other stresses for these forms, so they are shown here without a mark [src: goroh-dictionary].

Два, три, чотири

In the other cases, два and дві have the same forms. For the accusative, the orthography says “the same as the nominative or the genitive” [src: pravopys-2026, §105]. As with masculine nouns on the accusative page, the nominative form goes with things (ба́чу два буди́нки, I see two houses) and the genitive form with people and animals (ба́чу двох студе́нтів, I see two students).

П’ять and above

From five up, the numbers follow one pattern. Most cases have two forms, and both are correct [src: pravopys-2026, §105]:

The numbers from шість to два́дцять, and три́дцять, change in the same way. Шість, сім and ві́сім change their stem: шести́, семи́, восьми́; the instrumental of сім and ві́сім can also be сьома́, вісьма́ [src: pravopys-2026, §105].

Three numbers are simpler. Со́рок, дев’яно́сто and сто have a single ending -а in every case except the nominative and accusative: сорока́, дев’яно́ста, ста [src: pravopys-2026, §105].

In a long number, every part changes [src: pravopys-2026, §105].

Half: пів and півтора

• Пів means half. The noun after it is in the genitive singular, and пів is written as a separate word: пів годи́ни (half an hour), пів я́блука (half an apple) [src: pravopys-2026, §36, note].
• Півтора́ (one and a half) goes with masculine and neuter nouns, півтори́ with feminine nouns. They never change their form, and the noun after them is in the genitive singular: півтора́ кілогра́ма, півтори́ гри́вні [src: pravopys-2026, §107].

The usage guides mark півтора́ роки as an error: the correct form is півтора́ ро́ку (a year and a half) [src: goroh-usage].

Prices

A price is a number and гри́вня (hryvnia), the Ukrainian currency, with копі́йка (kopiyka, a hundredth of a hryvnia) for the change [src: ukma-ukrainian-foreign-language, Lesson 8]. Both are feminine, so they take одна́ and дві.

After the verb коштувати (to cost) and after за (for), the price is in the accusative. One with a feminine noun changes: одна́ гри́вня becomes одну́ гри́вню. Ти́сяча changes like a noun: коштує ти́сячу гри́вень. The other numbers stay as they are [src: ukma-ukrainian-foreign-language, Lesson 8; pravopys-2026, §105].

In everyday speech, the words for hryvnias and kopiykas are often left out, especially when the price has both. Одина́дцять три́дцять п’ять means 11 hryvnias 35 kopiykas [src: ukma-ukrainian-foreign-language, Lesson 8]. Shopping has more phrases for paying.

Ages

Ukrainian gives a person’s age with the dative and the word рік (year): literally, “to me are twenty years”. The dative page explains the pattern. Рік follows the same 1 / 2–4 / 5+ rule as every other noun [src: ukma-ukrainian-foreign-language, Lesson 8]:

Роки and років have no stress mark here, because the dictionary accepts two stresses for both [src: goroh-dictionary].
