Pronunciation

  • /besˈtem.mja/[1]

Forms

bestemmia f (plural bestemmie)[1] Old forms include Old Italian biastema, Old Italian biastemia, Old Italian blastemia and Old Italian bastemmia.[2] An old Tuscan form was Old Italian bestegna.[3][4]

Etymology

It is inherited from Late Latin blasphēmia (“slander; blasphemy”), the word of the Church writers, from Ancient Greek βλασφημία (blasphēmía, “slander, abusive speech”), reshaped after the verb bestemmiare.[5][6][4][1] The TLIO derives the noun from the verb.[2] DELI calls the Latin noun and verb learned loans, taken by Church Latin from Greek; the Greek word is an obscure compound of Ancient Greek φήμη (phḗmē, “speech, word”) with a first part not yet identified.[7]

The Romance forms do not continue the Latin spelling directly but a Vulgar Latin verb with ⟨-st-⟩, Vulgar Latin *blastemāre, supported by the form Latin blastema of an inscription from Gaul and by Medieval Greek.[8] Typical of Italo-Romance is the noun *blastemia formed beside it.[8][9] The ⟨-st-⟩ is explained as a dissimilation of the labials by Corominas, whom the LEI follows, and as the influence of Latin aestimō (“to value, to esteem”) by Parodi and Malkiel, for whom blasphemy was felt as a lack of esteem;[8][7] DELI explains it by the crossing of the Latin verb with some other verb.[8][7] Devoto–Oli and Sabatini–Coletti explain the first syllable of the modern form by a crossing with bestia.[10][9]

The verb survives as Romanian blestema, Friulian blestemâ, Old Occitan blastemar, Catalan blastomar and Spanish lastimar.[8] The learned blasfemia is a rare doublet, and biasimare comes from the same Greek family through Occitan.[11][7]

Earliest recorded meaning

The first record is in Andrea da Grosseto in 1268, a Tuscan text, for an imprecation or outrageous expression against God, the Virgin or religion.[2][4] Bono Giamboni, before 1292, lists bestemmia among the mortal sins with murder, theft, perjury and robbery.[7][12]

Semantic evolution

Old Italian used the word more widely than today: an outrageous expression against people, an insult or slander, a curse wishing someone ill, and even a misfortune or disease.[2] Dante speaks of a bestemmia di fatto, an offence to God by deeds rather than words.[2][12]

From Tasso (before 1595) it also meant an absurd statement, a use purists still rejected in 1855.[7] Catholic theology distinguishes heretical, simple and imperative blasphemy, and immediate blasphemy, against God, from mediate, against the Virgin, the saints and sacred things.[6]

The verb bestemmiare is recorded as biastemare in the 13th century and as bestemmiare in Dante (1300–1313), who also uses it for “to curse”;[7] Francesco da Barberino has it for “to swear” in 1314, and Carducci for “to speak a language badly”.[7]
