Forms

alegar (first-person singular present alego, first-person singular preterite aleguei, past participle alegado)[1] The 13th-century forms are alegar and allegar.[2] The spelling allegar was the main one until the 20th-century reforms: Vieira calls it the more correct form, and Figueiredo (1899) refers alegar to it.[3][4]

Etymology

It is borrowed from Latin allēgō (“to send as an envoy; to adduce”), written Old Galician-Portuguese alegar and Old Galician-Portuguese allegar in the 13th century.[2][5][6][1] Wiktionary calls it a learned borrowing, and Nascentes says it came by a semi-learned route.[1][7] The inherited outcome of the Latin verb survives only in Old French aleier and Old Occitan aleiar “to declare under oath”.[8] The same Latin verb gave Spanish alegar.[9]

The Latin verb is formed from ad- and lēgō (“to send as an envoy, depute”), and first meant “to send someone as one's agent”.[10][11] Machado and Houaiss note that the sense “to put forward as proof or justification” came later, in imperial Latin.[6][2]

Earliest recorded meaning

Houaiss and Cunha date the verb to the 13th century.[2][5] Lorenzo's chronology has decir e alegar e razonar “to say, allege and argue” in a document of 1324 known from an 18th-century copy, and Machado quotes a text of 1361: quando aconteçe que elles allegam... sseus Derejtos “when it happens that they plead their rights”.[12][6] From the start the verb belonged to the language of law.[12][6]

Semantic evolution

Notarial books of Santiago and Noia in the 15th century use it in fixed formulas renouncing the right dizer nen alegar leis nen dereitos “to cite or plead laws or rights” against a contract.[12] Cardoso (1569) glosses it with Latin cito and allego.[13] The modern senses widen from pleading in court to giving any reason, excuse or pretext, and to citing one's own services to support a claim.[2][14][15]
