Reimburse → It is formed from "re-" (meaning again) and "imbursare" (meaning to put in a purse). The word means to put back money into someone's purse or to repay someone for expenses incurred.
Think of putting money 'back' ('re-') into a 'purse' ('imbursare') — that's why reimburse means to pay someone back.
