Forms

deixar (first-person singular present deixo, first-person singular preterite deixei, past participle deixado)[1] The medieval form was leixar, far more frequent than the forms with d-.[2] Houaiss has leixe in 1091 and 15th-century forms such as lejxarom, leyxedes and lleixou.[3] Cunha dates dexar and deyxar to the 13th century and deixar to the 14th.[2] Carolina Michaëlis, in her glossary of the Cancioneiro da Ajuda, held instead that leixar is the only old form, and that deixar rose from popular speech in the 15th century.[4]

Etymology

It is inherited from Latin laxō (“to widen, loosen; to let go”), whose medieval outcome was Old Galician-Portuguese leixar.[2][5][1][6] In Medieval Latin the verb mostly meant “to let, leave”.[5] The Latin verb is formed on laxus (“loose, wide”).[7][1] The learned laxar is a doublet.[1]

The initial /d/ has no agreed explanation.[2][6] The REW calls the d- forms unexplained and suggests the influence of dō (“to give”), as do García de Diego and the DLE.[8][9][10] Michaëlis derived the word from Late Latin *dēlaxō, with the /l/ treated as if it stood between vowels and lost, as in rezar.[4] Nascentes reports that Meyer-Lübke saw phonetic difficulties in that compound.[11] Wiktionary allows either the compound or the influence of the preposition de.[1]

The same shift is found in Galician deixar, Asturian dexar, Spanish dejar and Catalan deixar, while French laisser, Italian lasciare, Occitan laissar and Romanian lăsa keep the /l/.[8][1] The old Spanish form was Old Spanish lexar, recorded from 1055, and Old Spanish dexar appears about 1200.[12]

De Vaan derives the Latin adjective from an Indo-European word meaning “weak, faint”, related to langueō (“to be faint”);[13][1] Wiktionary gives it as Proto-Indo-European *(s)leg-s-ós.[13][1]

Earliest recorded meaning

Houaiss's earliest dates come from Machado's Latin charters: leixe in 1091 and the Latinised dexare in 1209.[3][5] In Galician-Portuguese texts a charter of 1258–1261 has non leixaran razoando por ante o Juiz “they had not stopped pleading before the judge”, and the Cantigas de Santa Maria say of a man that he leyxou seu irmão “left his brother”.[4] A cantiga by Gil Perez Conde has the sense “to allow”: non vos leixarei entrar “I will not let you in”.[4]

Semantic evolution

The medieval texts already have the main senses of today: to let go, to abandon, to refrain from (leixar de), and to allow.[4] In the cantigas d'amigo leixar a with an infinitive stood where today one says deixar de.[4] Notarial documents of Noia (1403–1443) use leixar with desembargar for handing over land, and a 15th-century register of Rianjo already writes deixo.[4][14] Morais (1813) records “to abstain” (deixar de fazer), “to permit” and “to bequeath”.[15] The modern dictionaries add “to put off”, “to omit” and “to leave alone”.[1][16]
