pay: [12] Etymologically, to pay someone is to ‘quieten them down by giving them the money they are owed’. For the word is closely related to English peace. It comes via Old French payer from Latin pācāre ‘pacify’, a derivative of pāx ‘peace’. The notion of the irate creditor needing to be appeased by payment led to the verb being used in medieval Latin for ‘pay’. The original sense ‘pacify, please’ actually survived into English (‘Well he weened with this tiding for to pay David the king’, Cursor Mundi 1300), but by the beginning of the 16th century it had virtually died out, leaving ‘give money’ in sole possession.
