Forms

escusar (first-person singular present escuso, first-person singular preterite escusei, past participle escusado)[1]

Etymology

It is inherited from Latin excūsō (“to excuse, plead as an excuse”), written Old Galician-Portuguese escusar in the oldest texts.[1][2][3] Nascentes takes it as a learned word.[4] The Latin verb is formed from ex- (“out of”) and causa (“cause; lawsuit”).[5][1][2] Lewis and Short explain it as “to release from a charge”.[6]

The same Latin verb is Galician escusar, Spanish excusar, Catalan excusar, Italian scusare and French excuser.[1] In French it was borrowed from Latin about 1120, first as Old French escuser.[7]

Earliest recorded meaning

Houaiss and Cunha date the verb to the 13th century, Cunha with the sense “to excuse, pardon, tolerate”.[2][3] In the cantigas d'amigo it means “to dispense with”, and in another cantiga a speaker complains nen vós nunca me escusastes / de servir per mia pessõa “nor did you ever let me off serving in person”.[8][9] The Crónica Troiana has it for “to excuse oneself”, “to clear of blame” and “to avoid”: o que a de seer nõ se pode escusar “what must be cannot be avoided”.[8]

Semantic evolution

The medieval senses, “to excuse”, “to exempt” and “to avoid”, are still those of the modern verb.[8][2] The noun escusa “excuse” is recorded from the 14th century, the adjective escusado “needless” from the 16th.[3] Morais (1813) puts first the sense “not to need something”, then “to spare, avoid” and “to excuse oneself”.[10] Figueiredo (1899) adds the intransitive use “not to be necessary”.[11]

In Portugal the verb also means “to free a room” in one regional survey, and “to do without” in another.[12]
