Forms

esquecer (first-person singular present esqueço, first-person singular preterite esqueci, past participle esquecido)[1] The old forms are escaecer and escaeçer (13th century), esquecer (14th) and esqueecer (15th).[2][3] The cantigas also have escaescer.[4]

Etymology

It is inherited from Vulgar Latin *excadēscō, written Old Galician-Portuguese escaecer in the oldest texts.[2][3][1][5] Houaiss and Cunha call the Vulgar Latin verb a frequentative, Nascentes an inchoative, of *excadō (“to fall out”), which is ex- with cadō (“to fall”).[2][3][5][6] The Latin verb goes back to Proto-Indo-European *ḱad- (“to fall”).[1][7] The verb replaced the Latin oblīvīscor.[5]

Between the old and the modern form the sources show an intermediate Old Galician-Portuguese esqueecer: Nascentes speaks of an assimilation in the group ⟨sc⟩ and a contraction of the vowels in hiatus ⟨ae⟩.[8][9][1]

The same Vulgar Latin verb is Galician esquecer and Old Spanish escaecer “to forget”; in the other Romance languages its descendants mean “to decline”, “to fall due” or “to befall”, as Italian scadere.[6][1]

Earliest recorded meaning

The verb, as escaecer, is recorded from the 13th century.[2][3] It is frequent in the cantigas d'amor, as in Pero Garcia Burgalês's dona que me fezess' escaecer “a lady who would make me forget” and João Soares Somesso's que me fez tod' escaecer “who made me forget everything”.[10]

Semantic evolution

The derivative escaecimento “forgetting” is as old as the verb.[3] Morais (1789) records, beside the transitive and reflexive uses, an intransitive sense “to lose feeling” (esqueceu-me um braço “my arm went numb”), which the Porto dictionary still lists as little used.[11][12] Modern usage adds “to leave something behind by oversight”, “to neglect, disregard” and, in the reflexive, “to be lost in thought”.[13][12][2] The adjective inesquecível “unforgettable” is of the 20th century.[3]
