Forms

peidar (first-person singular present peido, first-person singular preterite peidei, past participle peidado)[1]

Etymology

It is formed from Portuguese peido + -ar.[2][3][4][1] The noun goes back to Old Galician-Portuguese peido, from Latin pēditum (“fart”).[5][6][1] Nascentes's fuller dictionary of 1955 had derived the verb directly from Latin pēdō (“to fart”), but his later one takes it from the noun.[7][8]

The new verb displaced the older Old Galician-Portuguese peer, used in the satirical cantigas.[1][9]

Earliest recorded meaning

Houaiss's first date is Morais's dictionary of 1789, and he notes that the word must be older but, being taboo, reached the dictionaries late.[2] It is in fact already in Cardoso's dictionary of 1569, glossed by Latin pedo.[10] In the cantigas d'escarnho of the 13th century the verb is still peer: Non quer' eu donzela fea / que ant' a mia porta pea “I don't want an ugly girl farting at my door”, sings Afonso X.[9][11]

Semantic evolution

The old peer was also slang for dying.[9] Morais (1789) and Vieira (1871) define peidar simply as “to break wind”.[12][13] In Brazilian slang the verb has gained the senses “to fail, give out” and “to chicken out”.[1][14]
