Phraseology: Set Expressions and Idioms | Russian Grammar

A фразеологи́зм (phraseological unit, idiom) is a fixed multi-word expression whose meaning you cannot work out from the individual words. When a Russian says спустя́ рукава́ ("with sleeves let down"), nothing is happening to anyone's sleeves — it means "carelessly, in a slapdash way." The whole expression carries one indivisible meaning, and the grammar inside it is often frozen: you cannot change the word order, swap a synonym in, or even update an archaic form to its modern shape. This page treats idioms as a category — what makes them different from ordinary phrases, why their grammar looks "broken," and how to store and deploy them. Russian is exceptionally rich in this material, and a learner who places one well (Возьми́ себя́ в ру́ки) instantly sounds more native; a learner who translates one literally produces nonsense.

What makes a phraseologism different

Two properties define a true idiom, and both matter for learning.

1. Non-compositionality (the meaning is not the sum of the parts). Take води́ть за́ нос — literally "to lead by the nose." A learner who knows води́ть ("to lead"), за ("by"), and нос ("nose") still cannot derive the actual meaning, which is "to deceive someone, to string them along, to keep someone on a hook with empty promises." The expression has been lexicalized: it functions as a single dictionary entry that happens to be spelled with three words.

Не ве́рь ему́ — он уже́ полго́да во́дит тебя́ за́ нос.

Don't believe him — he's been stringing you along for six months now.

Я по́нял, что меня́ во́дят за́ нос, и переста́л отвеча́ть на звонки́.

I realized I was being played for a fool and stopped answering the calls.

2. Fixedness (you can't rearrange or substitute). In an ordinary phrase you can swap synonyms: большо́й дом / огро́мный дом both work. In an idiom you cannot: бить баклу́ши means "to idle, twiddle one's thumbs," but you can't say бить па́лочки or уда́рить баклу́ши — the verb and noun are welded together. The noun баклу́ши isn't even used outside this idiom in modern Russian; it survives only here, the way English "kith" survives only in "kith and kin."

Хва́тит бить баклу́ши — за рабо́ту!

Enough loafing around — get to work!

Всё ле́то он бил баклу́ши, а в сентябре́ удиви́лся, что нет де́нег.

He frittered away the whole summer, then in September was surprised he had no money.

💡

The practical test for whether something is a phraseologism: ask "could a learner who knows every word guess the meaning?" If no — store it as a single unit, like a vocabulary word with spaces in it. Do not try to parse it grammatically every time; that is exactly the wrong instinct.

Frozen grammar: why idioms look "wrong"

The most useful insight for an advanced learner is that idioms preserve grammar that the living language has discarded. An idiom is a fossil: the surrounding language evolved, but the idiom kept its old shape because it's stored and reproduced as a block, not regenerated from rules. Three kinds of fossil show up constantly.

Fossilized verbal adverbs

Засучи́в рукава́ means "with sleeves rolled up" → "energetically, putting your back into it." Grammatically засучи́в is a perfective verbal adverb (деепричастие) of засучи́ть. In ordinary speech verbal adverbs are bookish and somewhat rare (see verbal adverbs), but inside this idiom the form is completely normal and frequent — because nobody is "forming" it; they're reproducing a stored phrase.

Но́вый дире́ктор взя́лся за де́ло засучи́в рукава́.

The new director threw himself into the job, rolling up his sleeves.

Е́сли возьмёмся засучи́в рукава́, зако́нчим за неде́лю.

If we really put our backs into it, we'll finish in a week.

Its mirror image is спустя́ рукава́ ("with sleeves let down") = "carelessly, half-heartedly." Спустя́ here is an old verbal adverb of спусти́ть; in modern Russian спустя́ has been reanalyzed as a preposition ("after," спустя́ год "a year later"), but inside this idiom it keeps its ancient participial job. So the two sleeve-idioms are a perfect minimal pair: roll them up = diligently, let them down = lazily.

Он де́лает всё спустя́ рукава́, поэ́тому оши́бок мно́го.

He does everything slapdash, so there are lots of mistakes.

Нельзя́ относи́ться к экза́мену спустя́ рукава́.

You can't approach the exam half-heartedly.

Archaic case forms

Several idioms keep a noun in a case ending that modern grammar no longer uses. In ка́ши не сва́ришь ("you won't cook any porridge [with him]") = "you can't get anything done with that person / you'll get nowhere together," the form ка́ши is a partitive genitive — grammatical, but the whole frame (a 2nd-person singular generalized "you") is frozen.

С таки́м упря́мым партнёром ка́ши не сва́ришь.

With a partner that stubborn you'll never get anything done.

Frozen word order and number

Ни ры́ба ни мя́со ("neither fish nor meat") = "neither one thing nor the other, nondescript, wishy-washy, mediocre." The двойно́е "ни… ни…" frame and the order are locked; you can't say *ни мя́со ни ры́ба and keep the idiom.

Фильм како́й-то ни ры́ба ни мя́со — ни смешно́, ни стра́шно.

The film is sort of neither here nor there — not funny, not scary.

Он на собра́нии ничего́ не реши́л — ни ры́ба ни мя́со.

He decided nothing at the meeting — a complete nonentity.

A working set of high-frequency idioms

These ten are common, idiomatic, and safe to use. Learn each as a unit, with its government (the case or preposition it demands) baked in.

Idiom	Literal	Actual meaning
бить баклу́ши	to beat баклу́ши	to loaf, twiddle thumbs
води́ть за́ нос (кого́?)	lead by the nose	to deceive, string along
как сне́г на́ голову	like snow onto the head	out of the blue, unexpectedly
спустя́ рукава́	with sleeves down	carelessly, slapdash
засучи́в рукава́	with sleeves rolled up	energetically, hard at it
де́ло в шля́пе	the matter is in the hat	it's in the bag, sorted
ни ры́ба ни мя́со	neither fish nor meat	neither one thing nor the other
сесть в лу́жу	to sit down in a puddle	to make a fool of oneself, flop
брать / взять себя́ в ру́ки	take oneself into one's hands	to pull oneself together
ка́ши не сва́ришь (с кем?)	you won't cook porridge	you'll get nowhere with someone

"Out of the blue": как сне́г на́ голову

Note the stress shift onto the preposition: на́ голову (not на го́лову). This proclitic stress is itself a fossil and a giveaway that you're inside a set phrase.

Он свали́лся как сне́г на́ голову — без предупрежде́ния, пря́мо в во́скресенье у́тром.

He turned up out of the blue — no warning, on a Sunday morning no less.

Э́та но́вость для нас как сне́г на́ голову.

This news hit us completely out of the blue.

"It's in the bag": де́ло в шля́пе

A whole frozen clause meaning "the matter is settled, success is guaranteed." It functions as a stand-alone exclamation.

Подпиши́ вот здесь — и де́ло в шля́пе.

Just sign here and it's in the bag.

"To flop / make a fool of yourself": сесть в лу́жу

Perfective сесть / imperfective сади́ться. The mental image (sitting down in a puddle in front of everyone) is doing all the work.

Он хва́стался, что зна́ет фи́зику, а на экза́мене сел в лу́жу.

He bragged he knew physics, then fell flat on his face at the exam.

"Pull yourself together": брать / взять себя́ в ру́ки

The single most useful idiom on this page for active production — sympathetic, idiomatic, and perfectly natural in speech. The imperative comes from the perfective взять: Возьми́ себя́ в ру́ки. Built on the suppletive pair брать / взять.

Возьми́ себя́ в ру́ки, сейча́с не вре́мя пла́кать.

Pull yourself together, now is not the time to cry.

По́сле разво́да ей бы́ло тяжело́, но она́ взяла́ себя́ в ру́ки.

After the divorce it was hard for her, but she pulled herself together.

Idioms vs. proverbs vs. collocations

These three categories overlap in everyday talk but behave differently, and knowing which is which tells you how much freedom you have.

A collocation (e.g. принима́ть реше́ние "to make a decision") is conventional but partly compositional — the words still mean roughly what they say; you just have to know which verb Russian prefers.
An idiom / phraseologism (бить баклу́ши) is non-compositional and grammatically frozen — you store it whole.
A proverb (посло́вица, e.g. без труда́ не вы́тащишь и ры́бку из пруда́ "no pain, no gain") is a complete sentence offering folk wisdom; it's quoted, not slotted into your own sentence.

The practical line: a collocation slots into your grammar (you conjugate the verb, decline the noun); an idiom is dropped in as a block; a proverb is quoted whole, usually as a self-contained remark.

💡

For active speech, master perhaps a dozen idioms cold and deploy them sparingly. One well-placed Возьми́ себя́ в ру́ки signals fluency; a sentence stuffed with three idioms sounds like a textbook showing off. For listening and reading, aim much wider — recognize that an idiom is an idiom so you don't try to parse it literally and end up confused by "sleeves" and "porridge."

How this differs from English

English of course has idioms too ("kick the bucket," "spill the beans"), so the category transfers cleanly — the trap is item-by-item. The dangerous error for English speakers is calquing: translating an English idiom word-for-word into Russian, where it means nothing. "To pull someone's leg" is not *тяну́ть за́ ногу in Russian; the Russian equivalent is води́ть за́ нос. "It's raining cats and dogs" has no animal version in Russian (it's лить как из ведра́, "to pour as if from a bucket"). Because idioms are culturally specific and stored whole, you cannot generate the Russian one from the English one — you must learn the Russian unit independently, exactly as a separate vocabulary item.

The reverse error is just as common: hearing a Russian idiom and decoding it literally. If you hear ка́ши не сва́ришь and start picturing porridge, you've already lost the sentence. The mental switch is "this is a frozen unit, retrieve its stored meaning, don't parse the parts."

Common Mistakes

❌ Он во́дит меня́ за нога́.

Wrong word and wrong case — the idiom is води́ть за́ нос (deceive); 'leg' would be a literal calque of English and means nothing in Russian.

✅ Он во́дит меня́ за́ нос.

He's stringing me along.

❌ засучи́в рука́в

Number error — the idiom is fixed in the plural засучи́в рукава́ ('sleeves'); you can't singularize a frozen phraseologism.

✅ Он взя́лся за рабо́ту засучи́в рукава́.

He set to work rolling up his sleeves.

❌ Э́та но́вость как снег на го́лову.

Stress error — the set phrase moves the stress onto the preposition: как сне́г на́ голову. Modern на го́лову breaks the idiomatic feel.

✅ Э́та но́вость как сне́г на́ голову.

This news came out of the blue.

❌ Возьми́ себе́ в ру́ки.

Wrong reflexive case — it's the accusative себя́ (take oneself), not the dative себе́: взять себя́ в ру́ки.

✅ Возьми́ себя́ в ру́ки.

Pull yourself together.

❌ Он упа́л в лу́жу на экза́мене. (meaning: he flopped)

Wrong verb — the idiom for 'make a fool of oneself' is сесть в лу́жу (sit down in a puddle), not упа́сть (physically fall); упа́сть в лу́жу is just literally falling into a puddle.

✅ Он сел в лу́жу на экза́мене.

He fell flat on his face at the exam.

Key Takeaways

A фразеологи́зм is a fixed, non-compositional expression: its meaning is not the sum of its words (води́ть за́ нос = deceive, not "lead by the nose").
The grammar inside idioms is frozen — fossilized verbal adverbs (засучи́в / спустя́ рукава́), archaic forms, locked word order and number. Don't try to "fix" or rebuild it.
Store idioms as whole units, like multi-word vocabulary, with their government attached (води́ть за́ нос кого́, ка́ши не сва́ришь с кем).
Distinguish collocation (slots into your grammar) from idiom (dropped in whole) from proverb (quoted as a complete sentence).
Avoid calquing English idioms into Russian, and avoid decoding Russian idioms literally — both break comprehension. Use a few cold, recognize many.
