#10. Idioms & Fixed Expressions

Idioms can help you sound natural—but only if they’re universal, polite, and clear. On CELPIP, prefer fixed expressions used in emails, notices, and everyday services. Avoid slang, jokes, and culture-specific metaphors. Use the phrases below to soften tone, signal structure, and move conversations forward.

When idioms help (and when they don’t)

Use expressions that:

• clarify the relationship between ideas (as a result, in the meantime, going forward);
• make requests polite (would you mind…, I’d appreciate…);
• frame problems and solutions calmly (it appears that…, the best way forward is…).

Avoid expressions that:

• are culture-bound or slangy (hit the sack, break a leg, ballpark figure in formal writing);
• exaggerate or sound emotional (it’s a nightmare, it’s killing me);
• could be misread in official contexts (ASAP can feel pushy—use as soon as possible or at your earliest convenience).

A quick filter: Is it clear to any adult reader? Does it fit formal/neutral tone? Does it stay literal enough for policy/email contexts?

Register ladders (formal → neutral → friendly)

• We would appreciate … → We’d appreciate … → I’d really appreciate …
• At your earliest convenience → When you have a moment → When you get a sec (avoid in assessed writing)

Pick the version that fits the audience and channel. In assessed tasks, formal → neutral is the safest range.

Pairs that sound natural in Canadian English (fixed + collocation)

• file a complaint | submit an application | request an extension
• meet a deadline | waive a fee | escalate an issue
• provide identification | verify your address | confirm availability
• arrange an inspection | schedule a technician | renew a permit
• follow up on a ticket | refer the case | grant access

Common pitfalls to avoid

• Colourful metaphors: on thin ice, out of left field, slam dunk (culture-specific).
• Humour/sarcasm: can be misread in official contexts.
• Pushy closers: Thanks in advance can sound presumptive—use Thank you for your help with this.
• All-caps and exclamation marks: read as emotional.
• ASAP: acceptable in chat; in emails use as soon as possible or at your earliest convenience.

Plug-and-play lines you can reuse

• Request with reason + timeframe
  I’m writing to request an extension to June 15, as a result of a banking delay.

• Polite complaint + solution
  I’d like to report a recurring noise issue after 11 p.m. In the meantime, could you arrange an inspection?

• Status update
  The technician visited this morning; as a result, installation is scheduled for Friday 2–4 p.m..

• Boundary with alternative
  We’re unable to approve a full refund; however, we can apply a credit to your account.

• Closing with next step
  Please let me know if anything else is required. I’ll keep you posted.
