Etymology

It is borrowed from Latin absurdus (“out of tune; senseless”), a learned word.[2][3][4][5][1] Houaiss dates it to 1589.[2] Cunha and Machado put the first record in the 16th century.[2][3][4]

The same Latin word is Galician absurdo, Spanish absurdo, Catalan absurd, French absurde, Italian assurdo and Romanian absurd.[1][6] French has it from the early 12th century, first as Old French absorde.[7] Meyer-Lübke considers it doubtful that Spanish zurdo (“left-handed”) comes from the Latin adjective, which García de Diego accepts.[8][9]

The Latin adjective is formed from ab- and surdus (“deaf; muted”), and first described a discordant sound.[10][11] De Vaan explains it as “unheard of”, since “deaf” can mean both “not hearing” and “not heard”.[11] Wiktionary connects the simple adjective with Proto-Indo-European *swer- (“ringing, whistling”), a link de Vaan finds hard to square with the meaning.[1][11]

Earliest recorded meaning

Machado quotes the 16th-century friar Heitor Pinto: He cousa absurda não alimpar o trigo do joio “it is an absurd thing not to clean the wheat of the darnel”, already in the sense “contrary to reason”.[4] Houaiss's first date is 1589.[2]

Semantic evolution

Bluteau (1712–1728) and Folqman (1755) enter the noun, “an act that offends good reason”, with the phrase fazer absurdos.[12][13] Morais (1789) has both the adjective “repugnant to reason” and the noun, and the logical demonstração por absurdo, the proof by contradiction.[14] Vieira (1871) notes that the Latin word first meant “offending the ear” and only figuratively “offending reason”.[15]

In the 20th century the noun took on philosophical senses: in Kierkegaard the gap between true subjectivity and rational abstraction, and in the literary and philosophical existentialism of Camus and Sartre the lack of meaning in human existence, as in the teatro do absurdo.[2] Houaiss also records the noun for an impossible plan, a utopia.[2][16]
