Forms

acusar (first-person singular present acuso, first-person singular preterite acusei, past participle acusado)[1] Medieval texts write acusar and accusar, and the 15th century also accussar.[2] Until the spelling reforms the usual form was accusar, to which Vieira and Figueiredo refer acusar.[3][4]

Etymology

It is inherited from Latin accūsō (“to blame, accuse, charge”), written Old Galician-Portuguese acusar in the oldest texts.[2][5][6][1] Nascentes takes it to be a learned word.[7] For the Spanish verb, Corominas finds no firm reason to think so, although the REW implies it.[8]

The same Latin verb is Spanish acusar, Catalan acusar, French accuser and Italian accusare.[9][1] The Latin verb is formed from ad- and causa (“lawsuit, cause”).[10][1] The latter is from Proto-Italic *kaussā, of unknown further origin.[1] Its inherited outcome is cousa, now coisa.[11]

Earliest recorded meaning

The Cantigas de Santa Maria use the verb in the sense “to accuse, denounce someone to an authority”: E fórona acusar / ao Bispo do logar “and they went to accuse her to the bishop of the place”, and in cantiga 78 de taes cousas a el o acussaron “they accused him to him of such things”.[12][6]

Semantic evolution

In the medieval texts the verb meant “to charge, incriminate”, both in everyday use and in law; the Crónica Troiana uses it of someone “accused and exposed”, and the records of the Santiago council for bringing charges.[12] Barbosa's dictionary of 1611 already lists acusador and acusação beside the verb.[13] Cunha dates both to the 13th century.[5]

The weaker sense “to show, reveal” and the business use “to acknowledge receipt” of a letter are recorded in Aulete's and Houaiss's dictionaries.[2][14] Houaiss also has two nautical senses: to slacken a rope little by little, and to repeat an order to show it has been understood.[2]

Timeline
