Idiomatic language is explicitly mentioned in the Band 7 and above descriptors for IELTS Speaking — but it's also one of the most misused tools by candidates. Forced, memorised idioms dropped into answers where they don't quite fit can do more harm than good. This guide gives you a practical set of idioms organised by topic, plus guidance on using them naturally.
How Idioms Are Actually Scored
| Band | Lexical Resource Descriptor (Idiomatic Language) |
|---|
| Band 6 | Uses "some" less common vocabulary, but with limited flexibility |
| Band 7 | Uses "some idiomatic vocabulary" with "some inappropriate choices" |
| Band 8 | Uses a "wide range of vocabulary fluently and flexibly... including idiomatic" with only occasional errors |
| Band 9 | Uses idiomatic language "naturally and accurately" |
The key word at Band 7 is "some" — you don't need to pack every answer with idioms. A few naturally-used idiomatic expressions, deployed where they genuinely fit, demonstrate the flexibility examiners are listening for. One unnatural, forced idiom can do more damage than zero idioms — it signals memorisation rather than genuine fluency.
General Fluency Phrases (All Parts)
These aren't "idioms" in the strictest sense, but they're the natural connective phrases that fluent speakers use — and their absence is often what makes an answer sound stilted.
| Phrase | Use |
|---|
| "To be honest..." | Introducing a candid opinion |
| "I'd say that..." | Softening an opinion |
| "Off the top of my head..." | Signalling you're thinking/recalling |
| "That's a good question..." | Brief natural pause before answering (use sparingly) |
| "Now that you mention it..." | Connecting to something just discussed |
| "I guess what I mean is..." | Self-correcting/clarifying naturally |

Using Idioms Naturally — A Framework
Part 1 (Everyday topics, short answers)
Idioms here should be simple and conversational — "to be a big fan of," "to get on well with," "to unwind." Avoid complex or formal idioms in Part 1; they sound out of place in short, casual answers.
Part 2 (Long turn, 2-minute talk)
This is where idiomatic language has the most room to appear naturally, since you're constructing a more developed narrative. One or two well-placed idioms (e.g., "off the beaten track" while describing a place, "to get into" while describing a hobby) demonstrate range without forcing it.
Part 3 (Abstract discussion)
Idioms here tend toward society-level topics — "on the rise," "a double-edged sword," "to keep up with." These work well when discussing trends, causes, and effects in abstract discussion.
Common Mistakes
| Mistake | Why It Hurts | Fix |
|---|
| Forcing an idiom into every answer | Sounds memorised/rehearsed | Use idioms only where they fit naturally — zero idioms in an otherwise fluent answer is better than one forced idiom |
| Using idioms with incorrect meaning | Signals limited actual understanding | Only use idioms you fully understand, including their connotation (positive/negative/neutral) |
| Mismatched register (formal idiom in casual Part 1 answer) | Sounds unnatural | Match idiom formality to the question's context |
| Pausing visibly to "insert" a prepared idiom | Disrupts fluency, which is also scored | Idioms should support fluency, not interrupt it — if it breaks your flow, skip it |
