Forms

conversiō f (genitive conversiōnis); third declension[1]

Etymology

It is from convertō “to turn round” with the suffix -tiō.[2][1][3]

Earliest recorded meaning

The TLL says it is found from the Rhetorica ad Herennium onwards, and the OLD's earliest citation for a rhetorical figure is from it.[3][2] Köbler dates it 86/82 BC.[4]

Semantic evolution

It meant a turning round, rotation, revolution, as Cicero's conversiōnēs astrōrum “the revolutions of the stars”, and a partial turn.[2][5] It meant turning upside down, inversion, in medicine a prolapse, a change, a political upheaval, as in Cicero, and in Quintilian a paraphrase.[2] In rhetoric it named several figures: the repetition of a word at the end of clauses, antistrophe, the transposition of words, as “one must eat to live, not live to eat”, the turning of an opponent's argument, and a period.[2]

In Ecclesiastical Latin it meant a moral change, conversion.[6] Medieval Latin used it of conversion and of taking monastic vows.[7] English conversion came in the mid-14th century through Old French, first of religious conversion.[8]
