Pronunciation

  • IPA: /kənˈvɝʒən/; /kənˈvɜːʃ(ə)n/, /-ʒ(ə)n/ (UK)[1]

Etymology

It is Middle English conversioun, borrowed from Old French conversion (“change, transformation; entry into religious life”),[2][3][4] from Latin conversio (“a turning round; change”), a noun of action from convertere (“to turn around, transform”) (see convert), from com- and vertere (“to turn”).[3][2]

Earliest recorded meaning

The turning of a sinner to righteousness and the love of God: about 1340, in a Middle English Psalter;[2] the mid-14th century in Etymonline.[3]

Semantic evolution

A change from one religion to another, especially to Christianity, is from about 1400.[3] The general sense, transformation from one state to another, is from the early 15th century, probably before 1425 in Barnhart.[3][2] Turning round or revolving (1540) and turning back (1553) are obsolete senses.[5] In law, conversion is the wrongful use of another's property as one's own.[6][7] Changing a building to another use is from 1921,[3] and in rugby and American football a conversion is the kick or play that adds points after a try or touchdown.[6][7] Conversion disorder, hysteria, is from 1946.[3]
