Idioms and Phrases
Fixed expressions, figurative meaning, usage pitfalls, and practice.
What is an idiom?
An idiom is a fixed expression whose overall meaning is not the sum of its parts. A phrase may be literal or figurative; many set phrases are conventional collocations.
| Idiom / Phrase | Meaning | Example |
|---|---|---|
| hit the nail on the head | state something exactly right | Her analysis hit the nail on the head. |
| once in a blue moon | very rarely | I eat dessert once in a blue moon. |
| cost an arm and a leg | be extremely expensive | The vintage lens cost an arm and a leg. |
| under the weather | feeling unwell | He’s under the weather today. |
| a blessing in disguise | a good thing that seemed bad at first | The delay was a blessing in disguise. |
“Idioms add colour—use them where they sound natural for the audience and register.”
Key points
- Meaning is figurative, not literal.
- Form is often fixed (don’t alter words/order).
- Register matters (formal vs informal).
- Some are region-specific; avoid clichés in formal writing.
Transparency & Variation
Idioms differ in how “guessable” they are and how fixed their wording is.
Transparent
Nearly literal; easy to infer.
- see the light (understand)
- lose your way (become confused)
Semi-transparent
Part literal, part figurative.
- break the ice (start social ease)
- spill the beans (reveal secret)
Opaque
Meaning not inferable from words.
- kick the bucket (die)
- red herring (distractor)
Common Pitfalls
- Literal mistranslation: Don’t read break a leg literally.
- Morphing the set phrase: ❌ spill the bean → ✅ spill the beans.
- Register clash: Avoid casual idioms in formal policy or academic abstracts.
If unsure, search reputable sources to confirm form & context.
Natural vs Awkward
Prefer the standard form and typical collocations:
| Target Meaning | Natural | Awkward / Wrong | Why |
|---|---|---|---|
| Encourage good luck (theatre) | Break a leg! | Crack a leg! | Fixed wording; don’t substitute synonyms. |
| Reveal a secret | Spill the beans | Spill the bean | Plural is part of the idiom. |
| Start a conversation lightly | Break the ice | Crack the ice | “Break” is conventional; “crack” sounds odd. |
| Stop working (day’s end) | Call it a day | Call off the day | Wrong verb/particle; idiom is fixed. |
