An idiom (Ukrainian фразеологі́зм) is a phrase whose meaning is not the sum of its words. To kick the bucket has nothing to do with buckets; Ukrainian байдики́ би́ти 'to idle' has nothing to do with hitting anything. These phrases are frozen — you cannot translate them word-for-word, swap a word for a synonym, or rebuild them from logic. You learn them whole, with their register, and you recognise them instantly when a native uses them. Ukrainian idioms are unusually vivid and culturally rooted: people bake crayfish when they blush, wish each other neither down nor feather before an exam, and describe a tiny amount as as much as a cat has cried. This page gives you the high-frequency ones every speaker knows — with the literal picture, the real meaning, and a natural example.
Idioms about idleness, deception and effort
These three describe what people do — or fail to do. байдики́ би́ти (literally 'to beat байдики', an obsolete word for small wooden blocks) means 'to idle about, twiddle one's thumbs'. води́ти за но́са 'to lead by the nose' means 'to deceive, string along' — close to the English image but with за + accusative. замилювати / зами́лити о́чі 'to soap someone's eyes' means 'to pull the wool over someone's eyes, hoodwink', with the person in the dative.
Замість готува́тися до і́спиту, він ці́лий ти́ждень байдики́ бив.
Instead of preparing for the exam, he spent the whole week idling about. (байдики́ би́ти — 'twiddle one's thumbs'; the word байдики́ survives only in this idiom.)
Не дозволя́й, щоб тебе́ води́ли за но́са — вимага́й усе́ в письмо́вому ви́гляді.
Don't let them string you along — demand everything in writing. (води́ти за но́са — 'deceive, lead by the nose'.)
Цей звіт ли́ше замилює о́чі нача́льству, а реа́льні пробле́ми зали́шилися.
This report just pulls the wool over the bosses' eyes, while the real problems are still there. (замилювати о́чі + dative нача́льству.)
Idioms about quantity and luck
як кіт напла́кав 'as much as a cat has cried' means 'very little, next to nothing' — a wonderfully Ukrainian image. The luck idiom ні пу́ху ні пера́ 'neither down nor feather' is the equivalent of break a leg — said before an exam, interview or performance. Crucially, it has a ritual reply: До бі́са! ('to the devil!'). Wishing plain «уда́чі» is fine, but the idiom obliges the other person to answer До бі́са! — wishing too directly was traditionally thought to jinx the outcome, hence the back-to-front blessing and the deflecting curse in reply.
Гро́шей у нас лиши́лося як кіт напла́кав — до зарпла́ти тре́ба еконо́мити.
We've got next to no money left — we'll have to economise until payday. (як кіт напла́кав — 'a tiny amount'.)
— За́втра в те́бе захи́ст дипло́ма? Ні пу́ху ні пера́! — До бі́са!
'You're defending your thesis tomorrow? Good luck!' 'Thanks!' (ні пу́ху ні пера́ — 'break a leg', with the obligatory reply До бі́са!, literally 'to the devil!'.)
Idioms about emotion and the body
The body is a rich source of idioms. пекти́ ра́ків 'to bake crayfish' means 'to blush, go red' — from the way a crayfish turns red when cooked. трима́ти язи́к за зуба́ми 'to hold one's tongue behind one's teeth' means 'to keep quiet, hold one's tongue'. бра́ти / взя́ти но́ги в ру́ки 'to take one's legs in one's hands' means 'to hurry up, get a move on, dash off'.
Коли́ вчи́телька зачита́ла його́ запи́ску вго́лос, він аж ра́ків пік.
When the teacher read his note out loud, he went bright red. (пекти́ ра́ків — 'to blush'; here in the past пік.)
Про це нікому ні сло́ва — вмій трима́ти язи́к за зуба́ми.
Not a word to anyone about this — learn to hold your tongue. (трима́ти язи́к за зуба́ми — 'keep quiet'.)
Авто́бус уже́ від’їжджа́в, тож я взяв но́ги в ру́ки й помча́в до зупи́нки.
The bus was already pulling away, so I got a move on and dashed to the stop. (бра́ти но́ги в ру́ки — 'hurry, dash off'.)
Idioms about ease and fit
як ри́ба у воді́ 'like a fish in water' means 'in one's element, completely at ease'. Note it is not a simile for swimming — it's about belonging and comfort.
На сце́ні вона́ почува́ється як ри́ба у воді́ — нія́кого хвилюва́ння.
On stage she's completely in her element — no nerves at all. (як ри́ба у воді́ — 'in one's element'.)

Source-language comparison and register
For an English speaker, three things matter. First, idioms do not survive literal translation in either direction — it's raining cats and dogs becomes ллє як з відра́, never a word-for-word calque, and conversely як кіт напла́кав would be baffling rendered literally. Second, some idioms come with ritual responses: ні пу́ху ні пера́ obliges До бі́са!, just as English break a leg doesn't, so the pairing is part of the phrase. Third, register is built in: most idioms here are informal-to-neutral, fine among friends, family and colleagues, but you would not pepper a formal report with байдики́ би́ти. For the folk-and-proverb register more broadly see proverbs and folk style, and for fixed similes specifically see fixed comparisons.
For a Russian speaker: use the Ukrainian idioms, not Russian ones in Ukrainian clothing. Wish ні пу́ху ні пера́ (the form matches, but mind the Ukrainian spelling and stress) and reply До бі́са!; say байдики́ би́ти, замилювати о́чі, як кіт напла́кав. Watch the Ukrainian-specific letters and the apostrophe (від’їжджа́в).
Common Mistakes
❌ Сього́дні ллє дощ із кота́ми і соба́ками.
A calque of the English idiom — meaningless in Ukrainian. The Ukrainian idiom is ллє як з відра́ ('pours as from a bucket').
✅ Сього́дні ллє як з відра́.
It's pouring with rain today.
❌ — Ні пу́ху ні пера́! — Дя́кую!
The literal 'thank you' breaks the ritual — the fixed reply to ні пу́ху ні пера́ is До бі́са!
✅ — Ні пу́ху ні пера́! — До бі́са!
'Break a leg!' 'Thanks!' (lit. 'to the devil!')
❌ У ме́не є як кіт напла́кав гро́шей бага́то.
Contradiction — як кіт напла́кав means 'very little'; you cannot pair it with 'a lot'.
✅ У ме́не гро́шей як кіт напла́кав.
I've got next to no money.
❌ Він три́має язи́к між зуба́ми.
The frozen idiom is за зуба́ми ('behind the teeth'), not між ('between') — you cannot swap the preposition.
✅ Він три́має язи́к за зуба́ми.
He holds his tongue / keeps quiet.
❌ Перед екза́меном він пік ра́ка.
The idiom for blushing uses the plural ра́ків; the singular ра́ка changes it to a literal 'baked a crayfish'.
✅ Перед екза́меном він аж пік ра́ків.
Before the exam he was blushing furiously.
Key Takeaways
- Idioms (фразеологі́зми) are frozen and non-literal: learn the meaning whole, never decode word-for-word, never calque from English.
- Some carry ritual responses — ні пу́ху ні пера́ → До бі́са! — and the pairing is part of the idiom.
- The wording is fixed: за зуба́ми (not між), ра́ків (not ра́ка), ллє як з відра́ (not a cats-and-dogs calque).
- Most of these are informal-to-neutral — perfect for conversation, out of place in a formal document.
- Using the right idiom at the right moment is one of the clearest signals of real Ukrainian fluency.

- Light-Verb Collocations (Брати, Робити, Мати, Давати)B2 — The fixed light-verb + noun collocations Ukrainian prefers, where the verb is bleached and the noun carries the meaning — бра́ти у́часть 'take part', звертати ува́гу 'pay attention', роби́ти ви́сновок 'draw a conclusion', ма́ти ра́цію 'be right', дава́ти зго́ду 'consent' — each with its governed case, and why choosing the English-equivalent verb fails.
- Fixed Comparisons and IntensifiersB2 — Stock Ukrainian similes (як + noun) and intensifying collocations: бі́лий як сніг 'white as snow', голо́дний як вовк 'hungry as a wolf', хи́трий як лис 'cunning as a fox', здоро́вий як бик 'strong as an ox', спить як уби́тий 'sleeps like a log', ллє як з відра́ 'pours down', схо́жі як дві кра́плі води́ 'like two peas in a pod'; plus adverbial intensifiers (страше́нно ра́дий, смерте́льно вто́млений, укра́й ва́жливо) and reduplication (давни́м-давно́, ти́хо-ти́хо) — fixed pairs where the noun and the intensifier are set by tradition.
- Folk and Proverbial StyleC1 — The grammar of Ukrainian proverbs, folk songs, and oral tradition — a register with its own rules of generalization and parallelism. The generalized 2nd-person singular addressing 'anyone' (Що посі́єш, те й пожне́ш), the omitted copula with a dash (Сло́во — не горо́бець), the gnomic present for timeless truths, the correlative frames (хто…той, де…там, яки́й…таки́й, як…так), syntactic parallelism and rhyme, ellipsis, the expressive vocative, folk diminutives (соловейко, дівчинонька), archaic and dialectal lexis, and fixed oral formulas (жив-був, за гора́ми, за дола́ми). The insight English speakers miss: proverbial Ukrainian runs on the GENERALIZED 2nd-person addressing everyone, the correlative хто…той / де…там scaffolding, the gnomic present, and the dropped copula — so folk style is a recognisable grammar of generalization, not just old vocabulary; reading it is both comprehension and a stylistic skill.
- Proverb: «Язи́к до Ки́єва доведе́»B1 — A close reading of 'the tongue will lead you to Kyiv' — how до + genitive marks a destination and why the perfective future доведе names a single guaranteed result.
- Proverb: «Сло́во — срі́бло, мовча́ння — зо́лото»A2 — A close reading of the proverb 'word is silver, silence is golden' — how the dash replaces the verb 'to be' and how the neuter -ння verbal noun works.
- Stance and Opinion MarkersB1 — The comma-set parentheticals that let a Ukrainian speaker frame a proposition: opinion (на мою́ ду́мку / по-мо́єму 'in my opinion', я вважа́ю 'I consider', як на ме́не 'as for me'), certainty (безпере́чно 'undoubtedly', очеви́дно 'obviously', напе́вно 'surely'), hedging (ма́буть 'probably', мо́жливо 'perhaps', зда́ється 'it seems', ні́би / ні́бито 'supposedly'), evaluation (на жаль 'unfortunately', на ща́стя 'fortunately', чесно ка́жучи 'frankly'), and the reported-speech particle мовля́в — explaining that Ukrainian carries attitude through these comma-set adverbials, not through tone alone.
