Pronunciation

  • /ˌɹiː.ɪmˈbɜːs.mənt/[1]

Etymology

It is formed from English reimburse + -ment,[2][3] perhaps after French remboursement, recorded in Middle French before 1430;[2] Merriam-Webster takes it as probably borrowed from the French word.[4] reimburse combines re- (“back”) with the now archaic imburse (“to pay, enrich”), recorded from the 1530s,[3][2] perhaps after rembourser or Italian rimborsare.[2] imburse is from French embourser, from Old French em- (“in”) and borser (“to get money”), from borse (“purse”), from Medieval Latin bursa, the source of purse.[3]

Earliest recorded meaning

The repaying of a sum of money: 1591, in the records of the Convention of Royal Burghs of Scotland, the same year as the verb reimburse.[2] Etymonline dates the noun to the 1610s.[3]

Semantic evolution

The meaning has stayed close to the original: the act of paying back money that someone has spent or lost, or an instance of it.[2][4] Johnson (1755) defined it as reparation or repayment.[5] The verb was also used figuratively for refunding or disgorging, from 1725 to 1849.[2]
