Etymology
It is borrowed from Ancient Greek βλασφημέω (blasphēméō, “to speak ill of, slander”),[1][2][3][4] a verb that Etymonline derives from βλάσφημος (blásphēmos, “evil-speaking”).[5]
Spoken Latin wore it down: the TLL lists Old Italian biastimare, French blâmer and Spanish lastimar among its outcomes.[3] Etymonline traces English blame through Old French blasmer and a Vulgar Latin *blastemō to this verb, and blaspheme through Old French blasfemer.[5]
Earliest recorded meaning
It belongs to the Bible and to Church writers who quote it.[3][6] Tertullian has blasphēmāre nōmen Dominī, to blaspheme the name of the Lord,[2][7] and in the Vulgate Leviticus tells of a man cum blasphēmāsset nōmen Deī, “when he had blasphemed the name of God”.[3][8]
Semantic evolution
Its main sense was to speak impiously of God and sacred things,[2][5] but it also meant to revile or reproach a person, as in the Vulgate's First Chronicles,[2][5] and Christian writers used it of teaching heresy.[4] Medieval writers extended it to cursing, to treating someone badly and to calling something harmful.[4]
The reproach sense lived on in French blâmer and English blame, recorded from about 1200;[5] English took blaspheme itself from Old French in the mid-14th century.[5]
