Pronunciation

  • Brazil: /ˈpɔ/[1]
  • Portugal: /ˈpɔ/[1]

Forms

pó m (usually uncountable, plural pós)[1] Old Galician-Portuguese wrote poo, plural poos; the Galician General Estoria has poluo.[2][3] Feijó (1734) prescribes the plural pós and rejects poses.[4]

Etymology

It is inherited from Vulgar Latin *pulus, from *pulvus, a Vulgar Latin form of Latin pulvis (“dust”) that passed into the second declension; the oldest texts write it Old Galician-Portuguese poo.[3][5][1][6] Nascentes explains the new form by the model of neuters such as latus, onus and opus.[6] Houaiss and Nascentes trace the later steps: the /w/ was absorbed into the vowel before it, the /l/ between vowels was lost, and the two vowels that met merged into one.[3][6]

The same Latin word is Galician po, Spanish polvo, Catalan pols, Italian polvere and Romanian pulbere.[7][1] Old Spanish still had a singular Old Spanish polvos, which Corominas also derives from the neuter form.[8] French poussière is a derivative of Old French pous, from the same Vulgar Latin form.[9]

The origin of the Latin word is debated: Wiktionary gives the traditional derivation from Proto-Indo-European *pel- (“flour, dust”), comparing pollen (“fine flour”) and Ancient Greek πάλη (pálē, “dust, meal”).[1] De Vaan is sceptical: he reconstructs *pelH-u- (“chaff”) and compares palea (“chaff”).[10]

Earliest recorded meaning

The word is in the Cantigas de Santa Maria of the second half of the 13th century: one cantiga has que foss' en poo tornada “that she be turned to dust”, another fez logo dela poos “at once made dust of it”.[2][3] In the Crónica Troiana Polidamas falls from his horse and his helmet rolls ẽna terra et ẽno poo “in the earth and in the dust”.[2]

Semantic evolution

Besides dust, the word soon named powders: a cantiga d'escarnho of Martin Moxa already speaks of carrying off a great sack of someone's poos.[2][11] Morais (1813) lists the finest part of earth, stone or glass, gold dust, the pós of medicinal roots and hair powder, and the phrases nascer no pó “to be born in the dust, of low birth” and levantar do pó “to raise from a low condition”.[12] The old Caldas Aulete adds pó de arroz “face powder”, the figurative sense “something of no value”, fazer em pó “to destroy”, the Brazilian slang sense “cocaine” and a northern sense “snuff”.[13] Dust as what the body returns to is the sense of pó és e em pó hás de tornar-te “dust thou art, and unto dust shalt thou return”.[14]

Dialect surveys record further senses: powdery mildew in Portugal, and in Brazil the dirt winnowed from threshed beans and used coffee grounds.[15] The word passed into Guinea-Bissau Creole as po.[1]
