Forms

dimenticare (first-person singular present diméntico, first-person singular past historic dimenticài, past participle dimenticàto, auxiliary avére)[1] Old forms include Old Italian dementicare, Old Italian dementegare, Old Italian domenticare and Old Italian dismenticare.[2][3] Dismenticare is still used in some regions.[4][5]

Etymology

It is inherited from Late Latin dēmenticāre (“to go out of one's mind”), a verb of the Latin glosses.[6][7][8][3] DELI and Devoto derive it from dēmenticus (“out of one's mind”), made of dē- and Latin mēns (“mind”);[6][9][10] Nocentini from dēmentīre (“to lose one's reason”).[7] The LEI notes that the sense “to go mad” came first and has not survived, so that the Italian verb continues only the later sense “not to remember”.[3] Wiktionary starts from Vulgar Latin *dismenticāre with another prefix.[1]

The verb belongs to Italy: DEI finds it in the Italian area except the far South, and the LEI adds an Engadine form.[11][3] Dalmatian dementicur and Sardinian ismenticare were taken from Italian.[1] The Latin noun mēns goes back to Proto-Indo-European *mn̥-ti- (“thought, mind”).[12]

Earliest recorded meaning

The TLIO's first record is the Storie de Troja et de Roma, written in Roman dialect between 1252 and 1258.[2] The LEI finds dementicare in a Tuscan translation of Albertano da Brescia of 1268, and dimenticare in Brunetto Latini about 1260–1261.[3] DELI's first date is Bono Giamboni, before 1292, in the sense “to lose the memory of things”.[6][13]

Semantic evolution

Old Italian already had most of the modern senses: “to forgive” (14th century, Bible translations), “to leave out, not mention” (before 1342, Cavalca) and “to leave an object behind” (1353, Boccaccio).[6] The TLIO adds “to neglect someone”, “to give up a custom” and “to fail to do something”.[2] Cecco Angiolieri writes that poverty had made him almost forget his lady's name: “'l nome ho già quasi dimenticato”.[13]

Dimenticanza “forgetfulness” is recorded in Bono Giamboni, dimentico “forgetful” in Giordano da Pisa (1303–1306), and the jocular dimenticatoio, the imaginary place where forgotten things end up, before 1565 in Varchi.[6] Indimenticabile dates from the 18th century;[7][6] DELI thinks dimenticabile was drawn from it.[7][6] Tommaseo distinguished dimenticare, a more deliberate forgetting or neglect, from the pronominal dimenticarsi, which is often involuntary.[14]
