Pronunciation
- IPA: /ˈɪn.fə.dl̩/, /ˈɪn.fəˌdɛl/[1]
Etymology
It is inherited from Middle English infidele, borrowed from Middle French infidèle,[2][3][4][5] from Latin īnfidēlis (“unfaithful; in Late Latin, unbelieving”),[2][3][4][5][6] from Latin in- (“not”) + fidēlis (“faithful”).[2][3][4][5]
Earliest recorded meaning
From a Christian point of view, an adherent of a religion opposed to Christianity, especially a Muslim or Saracen (1470–85).[7][3][4]
Semantic evolution
By 1526 the word meant one who disbelieves in religion generally,[7][3][4] especially one in a Christian land who rejects Christianity.[7] It was also used to translate Arabic kāfir, and so from a Muslim or Jewish point of view meant a Christian or other non-believer (1534).[7][4][6] From 1606 it meant anyone who disbelieves a particular doctrine or principle.[7][2]
