Etymology

It is inherited from Middle English blasfemen,[2][3][4] borrowed from Old French blasfemer, modern blasphémer,[5][4][3][6] from Late Latin blasphēmō (“to speak irreverently of; to revile”),[4][5][7][8] from Ancient Greek βλασφημέω (blasphēméō, “to speak profanely, to slander”).[5][7][6][8] The OED records the French verb from the 12th century, the Anglo-Norman Dictionary from about 1300 and Etymonline from the 14th,[5][9][7] and the Latin one from Tertullian, late in the 2nd century.[5] The Middle English Dictionary gives both Latin and Old French as the immediate source.[2] Most dictionaries derive the Greek verb from βλάσφημος (blásphēmos, “evil-speaking”),[4][7][6][8][10] while the revised OED derives the adjective from the verb, and the verb from a first element of uncertain origin and φήμη (phḗmē, “words, speech”).[5] Klein also calls the first element uncertain;[6] Barnhart takes it as probably meaning "false",[3] and Ayto relates it to βλαπτικός (blaptikós, “hurtful”).[11] The second element is related to fame,[6] and the American Heritage Dictionary refers both to Proto-Indo-European *bhā-.[4] A worn-down form of the Latin verb gave blame, so that this verb is a classical reintroduction of the same word.[7][11][3] The noun blasphemy is recorded some 140 years earlier, probably before 1200.[3]

Earliest recorded meaning

To speak or act with contempt for God or holy things: 1340, in the Ayenbite of Inwyt: "Þet ha..zuereþ and blasfemeþ aye god and his halȝen".[2][5][3]

Semantic evolution

Ayto remarks on how little the word has changed in form and meaning since its Greek origins.[11] The transitive use, with God or something sacred as object, follows before 1382 in the Wycliffite Bible.[5] About 1405, in Chaucer's Summoner's Tale, the verb was extended to whatever is treated as sacrosanct,[5] in Chaucer's only use of it.[12] The sense "to slander" is recorded in Latin from the 6th century and in French from the 15th,[5] and in English from before 1400, of speaking ill of a person or thing.[5] Johnson (1755) gave both meanings, quoting Macbeth for the second: "does blaspheme his breed".[13] The OED now calls this secular sense rare,[5] though Merriam-Webster Unabridged and the American Heritage Dictionary still list it.[14][4] Middle English also had nouns of this spelling, all obsolete: one from Late Latin blasphemus, a blasphemer, used until 1460, also as an adjective until 1450,[5] and one from French blasphème, an insult or an act of blasphemy, used until 1583.[5][9]
