passenger: [14] Originally a passenger was a passager – someone who goes on a ‘passage’, makes a journey. The word was borrowed from Old French passager, at first an adjective meaning ‘passing’, which was derived from passage. The n began to appear in the mid-15th century, a product of the same phonetic process as produced the n of harbinger and messenger.
