Forms

pes m (plural pesos)[1] The DCVB records /pέs/, /pés/ and, in Mallorca, /pə́s/.[2]

Etymology

It is inherited from Old Catalan pes, which is inherited from Latin pēnsum (“a weight of wool given to be spun”), the neuter of the past participle of pendō (“to weigh”).[3][2][4][1][5]

Coromines thinks the word took the general sense "weight" already in Vulgar Latin, replacing classical pondus, since all the Romance forms come from it.[3] Medieval Latin has it as "weight" and "tax".[6] The Romance forms point to a Vulgar Latin form without /n/, which Wiktionary writes *pēsum.[1] The same Latin word is French poids, whose ⟨d⟩ is a late spelling after the classical Latin word, Italian peso and Occitan pes.[7][1][8] García de Diego, against Meyer-Lübke, derives Spanish peso from the verb pesar rather than from the Latin noun.[9]

The verb pesar comes from pēnsō, the intensive of the same Latin verb.[3]

Earliest recorded meaning

CICA's first record is a 12th-century text, the Greuges dels homes de Sant Pere de Graudescale.[10] Coromines dates the word to the beginnings of the language and quotes Llull's Llibre del gentil, where God will make the weighing (lo pes) of good and evil on the Day of Judgement.[3][11]

Semantic evolution

In trade the phrase aver de pes, goods sold by weight, appears in a Roussillon document of 1284;[3] Old French had avoir de pois, which survives in English as avoirdupois.[3] Medieval pes also meant the scales and the weights used with them, the right weight of a coin, and importance, as in Eiximenis's advice not to believe coses de pes hastily (1381).[12]

It also named the public weighhouse, often at a city gate, and the tax charged there: Barcelona had a Casa del Pes de la Farina by 1390 and a Pes dels Draps in 1436.[3][12] The DIEC2 adds the physical sense, mass times the acceleration of gravity, and the sporting weights.[13]

In Balearic speech pes is also a contraction of per and the article es, which has a separate origin.[13]
