English idioms and phrases

An idiom is a common expression whose meaning cannot be worked out from the individual words. “Break the ice” has nothing to do with ice — it means to start a conversation in an awkward situation. Idioms are a normal, everyday part of natural English, and knowing them is a clear sign of fluency.

Everyday examples include “a piece of cake” (very easy), “cost an arm and a leg” (very expensive), “under the weather” (slightly ill) and “hit the sack” (go to bed). This page lists over seventy common idioms and phrases, each with its meaning and an example sentence.

A phrase is any small group of words that work together (“in the morning”). An idiom is a special kind of phrase whose meaning is figurative, not literal (“spill the beans” = reveal a secret). All idioms are phrases, but most phrases are not idioms. People often say “idioms and phrases” together to mean common set expressions.

A few of the most useful: “hit the nail on the head” (be exactly right), “once in a blue moon” (very rarely), “get cold feet” (become nervous), “the ball is in your court” (it is your turn to act) and “a blessing in disguise” (a hidden good). The themed tables above give many more.

Because the meaning is figurative — you cannot translate the words one by one and arrive at it. “Pull someone’s leg” is about teasing, not legs. The fix is to learn each idiom as a single unit, always with an example, and to meet it in real reading and listening until it feels natural.

Learn them in small, themed groups — as this page does — and always with an example sentence, because the sentence shows both the meaning and how the idiom is used. Do not cram a long list; take a handful, use each in your own sentence, and test recall with the quiz. Meeting them again in films and reading fixes them for good.

To break the ice is to say or do something that relieves tension and gets a conversation started, especially among people who do not know each other. “The host told a joke to break the ice.” A related term is an icebreaker — an activity used for the same purpose.

English has thousands, but a few hundred cover almost everything you will hear in everyday speech. Master the common ones first — the seventy-plus on this page are a strong start — and pick up the rest naturally through reading, films and conversation rather than trying to memorise a dictionary.

Most idioms are neutral to informal and are very common in speech, which is why they make your English sound natural. In formal academic writing, use them sparingly and choose a plainer phrase where precision matters. In conversation, an email, or a story, well-placed idioms read as fluent and native.

An idiom is a set expression used inside a sentence (“he let the cat out of the bag”). A proverb is a complete sentence that states a piece of advice or a general truth (“actions speak louder than words”). Both are fixed and figurative, but a proverb stands alone as a saying.

Those are pairs that sound or look alike but differ in meaning — affect/effect, their/there/they’re, advice/advise. They are a different topic from idioms; we cover them, with the distinction for each pair, in the “commonly confused words” set on the vocabulary page.

Not as a named task, but they run through natural English. Recognising idioms is important for Interactive Listening and reading — if “out of the blue” stops you, the meaning slips — and using one or two naturally lifts your Speaking. So this is vocabulary that feeds the test, not a DET drill.

In Listening and Reading, knowing idioms keeps comprehension intact when a speaker uses them — which native-style input does constantly. In Speaking and Writing, a well-placed idiom (“it was a blessing in disguise”) sounds natural and idiomatic, which is what the Production subscore rewards. Use them accurately, though — a misused idiom stands out.

Among the most frequent everyday idioms are “a piece of cake”, “break the ice”, “under the weather”, “hit the sack” and “cost an arm and a leg”. They come up constantly in conversation, so they are the best ones to learn and use first.
