Forms

pentirsi (first-person singular present mi pènto, first-person singular past historic mi pentìi, past participle pentìtosi)[1] An archaic form is pentersi.[2][3][4]

Etymology

It is inherited from Latin paeniteō (“to cause regret; to be dissatisfied”), which in Late Latin also had a form of the conjugation in ⟨-īre⟩, recorded from the 7th century.[5][6][1] DEI calls it a semi-learned word spread by the Church.[7] The same verb gave Old French peneir, Occitan penedir and Catalan penedir-se.[6][7] French repentir, Spanish arrepentirse and Portuguese arrepender come instead from Medieval Latin repaeniteō, with the prefix re-.[6] GRADIT treats the word as the pronominal form of pentire.[8]

The Latin verb may be related to paene (“almost”), in the sense of not having enough;[5][6][1] the adverb itself has no certain cognates.[5][6][1] De Vaan finds the basic meaning of the stem to be missing or lacking, and finds neither the comparison with Sanskrit nor a proposed inherited preverb convincing.[9] The same Latin verb is the source of the learned penitente and penitenza.[6]

Earliest recorded meaning

DELI's first record is in Giacomo da Lentini, before 1250, with the sense “to feel sorrow or remorse for what one has done or failed to do”.[5][10] Nocentini dates the past participle, as pentutu, to the 11th century.[6]

Semantic evolution

The old participle was pentuto, used by Dante, beside pentito;[11][6] Old Italian also had pentuta “repentance”.[11][6] Dante states the moral rule assolver non si può chi non si pente (“one cannot be absolved who does not repent”).[2] Pentimento appears before 1257 in Bonagiunta Orbicciani; its sense “change of mind” is recorded in 1630 (Davila) and “correction in a text” before 1827 (Foscolo), a use that Ugolini criticised in 1855.[5]

In the 1980s journalists began to use pentirsi absolutely of terrorists and Mafia members who agree to cooperate with the courts, and pentito for such a person (1980), with the derivative pentitismo (1982).[4][6]
