Pronunciation

  • Classical: [ĩːˈfɫɛk.si.oː][1]
  • Ecclesiastical: [iɱˈflɛk.si.o][1]

Forms

īnflexiō f (genitive īnflexiōnis); third declension[1]

Etymology

It is formed from Latin īnflectō (“to bend, curve”) + -tiō,[2][1] the verb being in-1 and flectō (“to bend”).[1]

Earliest recorded meaning

It first appears in Cicero: in De oratore he praises a vigorous and manly bending of the sides,[2][3] laterum inflexione hac forti ac virili, meaning the bearing of an orator's body.[2][3]

Semantic evolution

Cicero also uses it for the modification of words and of speech.[2] After Cicero the TLL finds it first in Optatianus Porfyrius, Chalcidius and Nonius.[4] Ammianus Marcellinus uses it of the curve of the Bosporus,[3][5] and Macrobius made it a grammatical term for the change of a word's form.[3][6] Medieval writers used it of the bending of the body, of turns of phrase, of grammatical inflection and, in music, of a melodic turn or modulation.[7][8]

English inflection (early 15th century) is from this word; its grammatical sense dates from the 1660s.[9]
