rebate
Synonym discussion
Sense: noun/1
All four words involve getting money back or paying less, but they differ in timing and context. A rebate is a partial return of money after a purchase, often offered by a government (tax rebate) or a manufacturer (mail-in rebate). A refund is the broadest term — it can be full or partial and applies to returns of goods, cancelled services, or overpayments. Reimbursement is narrower: it covers expenses someone paid on behalf of another person or organisation (e.g., a business trip). A discount is different — it is subtracted before you pay, not returned afterwards. For example: 'I received a $200 tax rebate after filing my return.' vs. 'The store gave me a full refund when I returned the jacket.' vs. 'My employer provided reimbursement for my flight.' vs. 'Students get a 10% discount on tickets.'

Etymology
Comes from Old French 'rabattre', meaning 'to beat down' or 'to reduce'. The 're-' part means 'back' or 'again', and 'abattre' means 'to beat down'. So the original idea was of knocking down the price — and over time it came to refer to the money returned after an overpayment.
