Pronunciation

Forms

complexiō f (genitive complexiōnis); third declension[1]

Etymology

It is from Latin complector (“to embrace”) + -tiō.[2][1]

Earliest recorded meaning

The Rhetorica ad Herennium uses it of a summary that briefly concludes an argument, and of the coalescing of letters.[2] Köbler dates the work 86/82 BC.[3]

Semantic evolution

It meant encircling, and a combination or group, as Cicero's combinations and couplings of atoms.[2][4] In rhetoric and logic it was a summary, a dilemma in which either answer is refuted (“if he is wicked, why employ him; if good, why accuse him?”), and the fusion of vowels or syllables, synaeresis.[2] The TLL notes that it is found in prose writers such as the Rhetorica ad Herennium, Cicero, Seneca and Quintilian and often in later authors.[5]

In Late Latin, from Firmicus Maternus, it meant the physical constitution of the body.[6] Medieval Latin used it for temperament and the combination of humours, and also for an embrace and a collection.[7][8] English complexion is recorded from the mid-14th century, first of temperament.[9]
