marry: [13] Latin marīus meant ‘husband’ (it may go back to an Indo-European *mer-, *mor-, which meant something like ‘young person’ – Lithuanian has the related marti ‘bride’ – and in that case would denote etymologically ‘man who has been provided with a young woman as a bride’). From it was derived the verb marītāre ‘marry’, which passed into English via Old French marier. Marriage [13] likewise comes from Old French. [marry etymology, marry origin, 英语词源]
