You've met the dative as the case of the recipient (give the book to me) and as the case of the dative subject (Мне хо́лодно "I'm cold"). This page covers a third, easily missed source of datives: certain adjectives and predicatives that demand a dative complement the way a verb would. When you say "I'm glad to see you," "I'm grateful to you," "I need money," or "it's clear to me," Russian routes the person involved through the dative — and in the most important case, нужен, it does something that flatly contradicts English logic. These constructions are everywhere in real speech, so getting them right is a big step toward fluency. Most use the short form of the adjective; if that's new, see long vs short adjectives.
Adjectives that take a dative complement
A small but high-frequency set of short-form adjectives is followed by a dative. The person (or thing) toward whom the feeling or relation is directed goes in the dative:
| Adjective (short form) | Meaning | Pattern |
|---|---|---|
| рад / ра́да / ра́ды | glad (to see / of) | рад + dative |
| благода́рен / благода́рна | grateful (to) | благода́рен + dative |
| ве́рен / верна́ | faithful, true (to) | ве́рен + dative |
| изве́стен / изве́стна | known (to) | изве́стен + dative |
| знако́м / знако́ма | familiar (to) | знако́м + dative |
| подо́бен / подо́бна | similar (to) | подо́бен + dative |
| ра́вен / равна́ | equal (to) | ра́вен + dative |
The adjective still agrees with its own subject in gender and number (рад for a man, ра́да for a woman, ра́ды for plural), while the dative complement names whoever the feeling is aimed at:
Я о́чень рад тебе́!
I'm really glad to see you! — рад (a man speaking) + dative тебе́. A woman would say ра́да.
Мы всегда́ ра́ды гостя́м.
We're always glad of guests. — ра́ды (plural subject 'we') + dative plural гостя́м (го́сти → гостя́м).
Я о́чень благода́рна вам за по́мощь.
I'm very grateful to you for your help. — благода́рна (a woman) + dative вам.
Он всю жизнь был ве́рен свои́м при́нципам.
All his life he stayed true to his principles. — ве́рен + dative при́нципам.
The нужен construction: the needed thing is the subject
This is the one that breaks English intuition, so it deserves its own section. To say "I need X," Russian does not make "I" the subject of a verb "to need." Instead it builds a sentence that literally means "X is needful to me." The consequences:
- The needer goes in the dative (Мне, Тебе́, Ему́…).
- The needed thing is the grammatical subject in the nominative.
- The word нужен agrees with the needed thing, not with the person.
So нужен changes shape depending on what's needed:
| Needed thing | Form of нужен | Example |
|---|---|---|
| masculine sg | ну́жен | Мне ну́жен сове́т — I need advice |
| feminine sg | нужна́ | Мне нужна́ по́мощь — I need help |
| neuter sg | ну́жно | Мне ну́жно вре́мя — I need time |
| plural | нужны́ | Мне нужны́ де́ньги — I need money |
Read it as the Russian means it: "To-me is-needed help" → Мне нужна́ по́мощь. The feminine нужна́ agrees with по́мощь (which is feminine), not with the speaker. This is exactly backwards from English, where I is the subject and need agrees with I.
Мне нужна́ твоя́ по́мощь.
I need your help. — needer Мне (dative) + subject по́мощь (fem.) → нужна́ agrees with по́мощь.
Тебе́ нужны́ э́ти докуме́нты?
Do you need these documents? — plural докуме́нты → нужны́; needer Тебе́ in the dative.
Ему́ ну́жен но́вый телефо́н.
He needs a new phone. — masculine телефо́н → ну́жен; needer Ему́ (dative).
A close synonym, необходи́м (необходи́ма / необходи́мо / необходи́мы), "(absolutely) necessary," works identically: Мне необходи́ма ви́за "I really need a visa." The neuter ну́жно also doubles as the impersonal "must / need to" with an infinitive (Мне ну́жно идти́ "I need to go") — that overlap is covered on impersonal modals.
Predicatives of clarity, perception, and comfort + dative
A family of -о predicatives describes a state perceived by someone, and that someone — the experiencer — goes in the dative. These are the impersonal sentences with no nominative subject and a frozen neuter form:
| Predicative | Meaning | Example |
|---|---|---|
| поня́тно | (it's) clear / understood | Мне поня́тно — it's clear to me |
| я́сно | (it's) clear | Всем я́сно — it's clear to everyone |
| ви́дно | (it's) visible / one can see | Тебе́ ви́дно? — can you see? |
| слы́шно | (it's) audible / one can hear | Тебе́ слы́шно? — can you hear? |
| интере́сно | (it's) interesting | Мне интере́сно — I'm interested |
| тру́дно / легко́ | (it's) hard / easy | Ему́ тру́дно — it's hard for him |
— Тебе́ всё поня́тно? — Да, мне всё я́сно.
— Is everything clear to you? — Yes, it's all clear to me. — both поня́тно and я́сно take the dative experiencer (Тебе́, мне).
Говори́ гро́мче, мне пло́хо слы́шно!
Speak louder, I can't hear well! (lit. 'to me it's badly audible') — слы́шно + dative мне.
Э́то изве́стно всем.
This is known to everyone. — изве́стно (neuter) + dative всем; here изве́стно behaves like a predicative.
How this differs from English
The deep difference is that English makes the experiencer the grammatical subject ("I need," "I can see," "I'm glad"), while Russian frequently makes the experiencer a dative and lets the thing be the subject — or has no subject at all. With нужен this flips agreement entirely: the verb-like word agrees with the thing needed, not with the person. English speakers reliably produce Я нужен по́мощь ("I need help") by analogy with English, when Russian wants Мне нужна́ по́мощь. And because English attaches these relations with prepositions (grateful to, faithful to), learners want to insert к — but the bare dative already means "to." Treat these constructions as a set: when the person is an experiencer of a state or a needer, they tend to be dative, not nominative.
Common Mistakes
❌ Я нужна́ по́мощь.
Incorrect — the needer can't be the nominative subject; the needed thing is the subject and the needer is dative.
✅ Мне нужна́ по́мощь.
I need help. — Мне (dative needer) + по́мощь (subject) → нужна́ agrees with по́мощь.
❌ Мне ну́жен де́ньги.
Incorrect — нужен must agree with the needed thing; де́ньги is plural, so it's нужны́.
✅ Мне нужны́ де́ньги.
I need money. — plural де́ньги → нужны́.
❌ Я благода́рен к вам.
Incorrect — благода́рен takes a bare dative; don't add к to translate English 'to'.
✅ Я благода́рен вам.
I'm grateful to you. — bare dative вам.
❌ Я рад тебя́.
Incorrect — рад takes the dative, not the accusative; тебя́ is accusative.
✅ Я рад тебе́.
I'm glad to see you. — рад + dative тебе́.
Key Takeaways
- A set of short-form adjectives governs a bare dative: рад, благода́рен, ве́рен, изве́стен, знако́м, подо́бен, ра́вен (Я рад тебе́, благода́рен вам, ве́рен при́нципам). No preposition — the dative itself means "to."
- The adjective agrees with its own subject (рад / ра́да / ра́ды) while the dative names whoever the feeling is aimed at.
- The нужен construction is inverted: the needer is dative, the needed thing is the nominative subject, and нужен/нужна́/ну́жно/нужны́ agrees with the thing needed (Мне нужна́ по́мощь, Мне нужны́ де́ньги). необходи́м works the same way.
- -о predicatives of clarity/perception/comfort take a dative experiencer: Мне поня́тно, Тебе́ слы́шно?, Ему́ тру́дно.
- The unifying logic: where English makes the experiencer the subject, Russian often makes them a dative — and lets the thing (or nothing) be the subject.

- Dative Subjects: Feelings, Age, NecessityA2 — In a signature Russian construction the logical subject — the person experiencing a state — stands in the DATIVE, not the nominative, and there is often no nominative subject and no real verb at all. Feelings: Мне хо́лодно (I'm cold), Ему́ ску́чно (he's bored). Age: Мне два́дцать лет (I'm 20). Necessity/permission: Мне на́до идти́ (I have to go), Здесь нельзя́ кури́ть (you can't smoke here). Liking: Мне нра́вится му́зыка (music is pleasing to me — the liked thing is the nominative subject!). The verb, when present, is frozen neuter. This is where English speakers most resist Russian, and mastering it is the gateway to sounding native.
- Dative: FormsA2 — The dative (да́тельный паде́ж) answers кому? (to whom?). Singular: masc/neuter -у/-ю (столу́, музе́ю, окну́, мо́рю), feminine -а/-я → -е (кни́ге, неде́ле), feminine -ь → -и (но́чи), and the -ия/-ие → -ии exception (Росси́и, ле́кции). Plural is uniform across all genders: -ам/-ям (стола́м, кни́гам, моря́м, музе́ям). The pronoun datives are мне, тебе́, ему́/ей, нам, вам, им, себе́. The trap: the feminine dative singular looks identical to the prepositional (both кни́ге), so the FORM is shared but the FUNCTION differs.
- Dative with Impersonal Modals (можно, нужно, нельзя, пора)A2 — Russian expresses most modality about people with a frozen pattern: dative person + impersonal word + infinitive. Мне на́до идти́ (I have to go), Вам мо́жно войти́ (you may come in), Ему́ нельзя́ кури́ть (he mustn't smoke), Нам пора́ е́хать (it's time for us to go), Тебе́ тру́дно поня́ть (it's hard for you to understand). Past/future insert frozen neuter бы́ло/бу́дет (Мне на́до бы́ло уйти́). The experiencer is the DATIVE — there's no nominative 'I'. Plus the agreeing ну́жен/нужна́/ну́жно/нужны́ for needing a thing (Мне нужна́ по́мощь, Мне нужны́ де́ньги).
- Short-Form AdjectivesB1 — Russian adjectives have a second, predicate-only form — the short form — that marks only gender and number, never case. Masculine takes a bare stem (за́нят, здоро́в, ра́д), feminine -а (занята́, больна́), neuter -о (за́нято, закры́то), plural -ы/-и (за́няты, закры́ты). Short forms appear after the zero copula (Он за́нят; Дверь закры́та; Я гото́в) and often express a TEMPORARY state, against the long form's permanent/categorizing meaning: Он бо́лен ('he's ill right now') vs Он больно́й ('he's sickly'). A few adjectives — рад, до́лжен, согла́сен, нужен, гото́в — live mainly or only in the short form. Short forms cannot be used attributively.
- Which Adjectives Have Short Forms (and Common Ones)B2 — Only QUALITATIVE adjectives (ones naming a gradable quality — happy, busy, sure) form short forms; relational adjectives (деревя́нный 'wooden', ру́сский 'Russian') never do. This page gives the highest-frequency short-form adjectives you'll actually use as predicates — рад (which exists ONLY as a short form), до́лжен, согла́сен, уве́рен, гото́в, за́нят, свобо́ден, бо́лен, прав, винова́т, похо́ж, нужен — and the fleeting-vowel pattern in the masculine (у́мный → умён, по́лный → по́лон).

- The Dative: Functions SummaryA2 — The case of the recipient and the experiencer on one page: indirect object (дать дру́гу), dative-experiencer states and age (Мне хо́лодно, Мне два́дцать лет), Мне нра́вится, dative-governing verbs (помога́ть, звони́ть), the modals на́до/ну́жно/мо́жно/нельзя́, and the prepositions к and по — a compact endings-and-uses recap.
