词源
From Middle English declinen, and ultimately Latin declīnō (“to bend, turn aside, deflect, inflect, decline”, from dē- (“down”) + clīnō (“to bend, to incline”)), from Proto-Indo-European *ḱley- (English lean). The senses arrived from two separate pathways in Middle English: * The grammatical sense came from Old English declīnian, which was borrowed directly from the Latin etymon. * All senses except the grammatical sense were derived from those of Old French decliner. Old French itself borrowed the verb from Latin.
