reimburse

Imagine you bought snacks for the office party, and your coworkers later paid you back. That is reimbursement. To reimburse someone is to repay them for money they spent for you or for a shared plan. It often happens with work costs; if you travel for business, your company will likely reimburse you for things like hotel bills and plane tickets. You can also be reimbursed, which means you get that money back. Think of it as making things even again after someone used their own money first.

To reimburse means to pay someone back for expenses they have already paid, usually because there was an understanding that those costs would be covered later. It is close to a refund, but it usually focuses on paying back a person who used their own money first.

Think of it like this: your insurance company might reimburse you for medical bills after you have already paid the hospital. Or, if you pay for a friend's lunch because they forgot their wallet, their later payment to you is a reimbursement for that out-of-pocket cost. It is most common in professional contexts. Employees are often reimbursed for travel expenses, mileage, or supplies purchased for work.

The key part of reimbursement is that the person receiving the money spent it earlier. You do not reimburse someone before they spend the money; you repay them after. You might say, "The company will reimburse me for all reasonable business expenses," or "I submitted a claim to be reimbursed for the repair costs."

While the word is mainly used in financial situations, the central idea is restoring money that someone spent. In simple terms, reimbursement is about making someone even again after they used their own money to cover a cost that another person, company, or group was supposed to pay.
