Pronunciation
Forms
recusar (first-person singular present recuso, first-person singular preterite recusei, past participle recusado)[1] Houaiss's historical forms include refusase (15th century) and refusar (1563); refusar survives as a rare synonym.[2][3] Morais (1813) and Vieira still define recusar by refusar.[4][5]
Etymology
It is borrowed from Latin recūsō (“to object, to refuse”), a learned word.[2][6][1][7] The Latin verb is formed from re- and causa (“cause, case”), and was first a legal term, “to put in an objection”.[8][1]
The Latin word is also Galician recusar, Spanish recusar, Catalan recusar and Italian ricusare.[1][9] In French it lost its -c- and gave the popular French ruser.[1]
Earliest recorded meaning
Houaiss and Cunha date it to the 14th century, with the sense “to reject, not accept”.[2][6] The Livro dos Mártires of 1513 has it.[10]
Semantic evolution
Bluteau's examples are all of declining an offer: an office, an embassy, a title, a just condition.[11] Morais (1813) adds the legal recusar o juiz “to reject a judge as biased”, from the Ordenações.[4] Aulete records the senses “to refuse to grant” and, with an infinitive, “to refuse to do”.[12] In law it now also means to reject a witness, and reflexively to stand down from a case.[2][1]
