Pronunciation

  • IPA: UK /dɪˈklaɪn/, /dəˈklaɪn/, US /dɪˈklaɪn/[1]

Etymology

The verb is inherited from Middle English declinen, borrowed from Old French decliner (“to turn aside, sink”),[2][3][4] from Latin dēclīnāre (“to bend, turn aside, inflect”),[2][3] from dē- (“from”) and clīnāre (“to bend”),[2][3][4] from Proto-Indo-European *klei- (“to lean”).[2] It is related to lean.[3][5] The noun is Old French declin, from the verb.[3][2]

Earliest recorded meaning

The noun, a sinking into a weaker or worse condition: before 1325 in Barnhart, before 1327 in the OED.[3][6] The verb, to turn aside or deviate, is from about 1325 in the OED and before 1376, in Piers Plowman, in Barnhart.[6][3]

Semantic evolution

The grammatical sense, to inflect a noun or adjective, is from the late 14th century.[2] Because de- was read as “downward”, the sense shifted: to bend or slope down is from before 1420 in Barnhart and about 1400 in Etymonline.[3][2] To refuse politely is from about 1631 in Barnhart, the 1630s in Etymonline.[3][2] As a noun, the later years of life, short for decline of life, is from 1711,[2][6] and a wasting disease such as tuberculosis from 1783.[6] A fall in prices is from 1885.[6]
