Etymology

It is inherited from Middle English blasfemous,[2][3] borrowed from Late Latin blasphēmus (“evil-speaking, blasphemous”) with its ending replaced by -ous,[4][5][6][7] or perhaps borrowed from Middle French blasphemeus (late 14th century).[4][3] The Latin adjective, recorded from the 4th or 5th century, is from Ancient Greek βλάσφημος (blásphēmos, “evil-speaking, slanderous”),[4][8][5][9] which in Hellenistic Greek also meant blasphemous.[4] The Greek adjective is from the verb meaning to speak profanely or to slander,[4][3] and its second element is φήμη (phḗmē, “speech”);[4][10][11] the OED calls the first element of uncertain origin, while Dictionary.com and Collins connect it with a word for harm or evil.[4][10][11]

Earliest recorded meaning

Showing contempt for God or sacred things: before 1425, of blasphemous swearing, in the Lanterne of Light.[4][2] Etymonline dates it to the early 15th century,[3] Merriam-Webster Unabridged to the 15th century.[9]

Semantic evolution

The English adjective kept for a time the older Greek sense of slander: from 1551 to 1678 it could mean abusive or defamatory.[4][5] The religious sense has remained the main one, used especially of oaths and curses;[4][9] Johnson (1755) defined it as "impiously irreverent with regard to God".[12] Since 1846 it has also been used by exaggeration of disrespect toward anything treated as sacrosanct.[4]
