Forms

Etymology

It is borrowed from Ancient Greek βλάσφημος (blásphēmos, “evil-speaking”).[1][2][3][4]

Earliest recorded meaning

Tertullian is the first author Lewis and Short cite for it, as a noun meaning one who speaks impiously of God and divine things.[2]

Semantic evolution

A word of Christian Latin,[2] it means reviling or defaming, as in Prudentius,[2] and as a noun a blasphemer.[2][5] The Vulgate uses it in Leviticus and in the First Letter to Timothy,[2][6] and Jerome in his letters.[2]

Medieval Latin used it for evil-speaking and blasphemous, and in a passive sense for a person of bad reputation, a notorious criminal.[7][3] English blasphemous comes from it, directly or through Old French.[4]
