In short

The dative case (давальний відмінок) answers the questions кому́? (“to whom?”) and чому́? (“to what?”). Its core job is to mark the recipient — the person you give, show, tell, or write something to. Ukrainian also uses it for a second, very frequent job: the experiencer. In impersonal sentences about feelings, needs and states, the person who feels stands in the dative while there is no nominative subject at all — мені́ тре́ба, мені́ хо́лодно. A close relative is мені́ подо́бається, which puts the experiencer in the dative the same way but does have a nominative subject: the thing you like (Мені́ подо́бається це мі́сто).

The rule

1. The recipient (indirect object). Where English says “give something to someone” or “buy something for someone”, Ukrainian usually just puts the person in the dative — no preposition:

• Я дав бра́тові кни́гу. — I gave my brother a book.

A small but everyday set of verbs takes the dative directly, where English uses a plain direct object. Learn them together: допомага́ти (help), дя́кувати (thank), телефонува́ти / дзвони́ти (phone), ра́дити (advise), заважа́ти (disturb). “I help him” is Я допомага́ю йому́, not an accusative.

2. The experiencer (давальний суб’єкта стану). In impersonal one-member sentences the feeler goes in the dative, and the predicate is a special adverb or a modal word. There is no nominative subject and no present-tense form of «бути»:

• Мені́ хо́лодно. — I am cold.
• Мені́ ціка́во. — I find it interesting.
• Мені́ тре́ба / потрі́бно відпочи́ти. — I need to rest.

With подо́батися (“to be pleasing”) the thing you like is the grammatical subject (nominative) and the liker is dative — the mirror image of English: Мені́ подо́бається му́зика = “music is pleasing to me”. Age works the same way: Мені́ два́дцять ро́ків (“I am twenty”).

Forms & patterns

Singular endings by gender and stem type. Animate masculine nouns favour -ові/-еві; the shorter -у/-ю is also standard.

In the plural the ending is uniform -ам/-ям for every gender: студе́нтам, вчителя́м, ді́тям, дру́зям.

Personal pronouns (memorize these — they carry most of the experiencer sentences):

Examples

Common mistakes

• Я телефону́ю дру́га -> Я телефону́ю дру́гові — телефонува́ти/дзвони́ти govern the dative, not the accusative.
• Я допомага́ю мою́ сестру́ -> Я допомага́ю мої́й сестрі́ — допомага́ти takes a dative object.
• Дя́кую тебе́ -> Дя́кую тобі́ — дя́кувати takes the dative; “thank to you”, literally.
• Я хо́лодно -> Мені́ хо́лодно — the experiencer is dative; there is no nominative “I” here.
• Я тре́ба відпочи́ти -> Мені́ тре́ба відпочи́ти — треба/потрібно need a dative feeler, never a nominative one.
• Я подо́баюся це мі́сто -> Мені́ подо́бається це мі́сто — with подо́батися the liked thing is the subject; the liker is dative.
• Мені́ є хо́лодно -> Мені́ хо́лодно — no copula «бути» in the present tense.

Tips

• English “to/for + person” after give, show, tell, write, buy is normally a bare dative in Ukrainian, with no preposition: Я показа́в дру́гові фо́то.
• Keep a fixed list of dative-governing verbs: допомага́ти, дя́кувати, телефонува́ти, ра́дити, заважа́ти. They feel transitive in English but are dative in Ukrainian.
• Feelings and needs are impersonal: person in the dative + a predicate word (хо́лодно, ціка́во, ва́жко, тре́ба, мо́жна). Drop the nominative subject and the present-tense “to be”.
• подо́батися flips the word order of English like: the thing enjoyed is the subject, the enjoyer is dative.
• Watch the consonant swap in feminine -га/-ка/-ха before the dative -і: по́друга -> по́друзі, рука́ -> руці́, кни́жка -> кни́жці.
• Age and time use the dative feeler: Скі́льки тобі́ ро́ків? — Мені́ де́сять ро́ків.
• Use polite ви for the dative вам with strangers and elders; тобі́ only with friends, family and children.
