How to decide: Imagine the recipient reading it aloud. If it sounds accusing or emotional, choose the neutral option.
| Choice | Use it when… | Bad swap to avoid |
|---|---|---|
| repair | you will fix the same item | replace (means new item) |
| replace | you will swap with a new one | repair when it’s beyond repair |
| postpone | you will move to a later time (still happening) | cancel |
| cancel | the event/action will not happen | postpone |
| reschedule | you will set a new time (neutral) | delay if time is unknown |
| quote | a price before work, may change | estimate isn’t always binding either—state terms |
| estimate | an approximate cost/time | treat as final price |
| bill | the document asking for money (neutral) | invoice is formal/for business |
| invoice | formal request with details/reference | bill in formal writing |
| cost | total amount required | expense (a recorded cost) / fee (fixed charge) |
| authorize | give official permission | approve (decision), permit (allow by rule) |
| approve | accept a proposal/claim | authorize when a signature/power is needed |
| address (a problem) | take steps toward a solution | fix (implies solved) |
| resolve | problem is fully solved | address when outcome is uncertain |
Collocational fit (what native speakers actually say):
Choose the first word that satisfies all four.
Rewrite once for register and once for degree.
Sample answers (one of many good options):
Key (suggested): 1) replace 2) verify 3) postpone 4) affordable 5) resolve (if sure) / address (if steps only) 6) submit 7) waived 8) concerned 9) fee 10) approve (decision) → authorize (finance system)
Polite request:
I’d like to request a refund for the damaged item. I’ve attached the invoice as proof of purchase.
Complaint + solution focus:
I’m reporting a recurring noise issue after 11 p.m. Could you enforce the quiet-hours policy or arrange an inspection?
Soft disagreement (nuanced):
I understand the concern; however, the contract permits cancellations with 24 hours’ notice.
Recommendation with degree control:
It would be reasonable to postpone installation until the weather improves.
