deu m or f[1]
Etymology
The word for the number ten is inherited from Latin decem (“ten”).[2][3][4][5][1]
The same Latin word is Old Occitan detz, French dix, Spanish diez, Italian dieci and Romanian zece.[6][7]
The Latin numeral goes back to *dekem and *déḱm̥, cognate with δέκα (déka) and the English word ten.[1][8]
Earliest recorded meaning
Coromines and the GDLC place the word in the oldest texts of the language.[2][5] Llull writes of los deu manaments, the Ten Commandments, in the Llibre del gentil.[9]
Semantic evolution
The ordinal was formed with the Romance suffix -è from Latin -ēnus: the old form was deè, feminine deena, from a prehistoric dezen with the regular loss of intervocalic /z/;[9] desè, with the /z/ restored, finally won out, partly because a contracted masculine dè would have been too short and too far from deu.[2] From the feminine come dena, each set of ten beads of a rosary, and desena.[2] Desembre went through the same changes: Desclot writes dehembre, and a document of 1374 dembra.[2]
Bruguera groups with the numeral the compounds dinou, disset and divuit, and degà from Latin decanus.[4]

Pronunciation
Forms
deu f (plural deus)[1] Old Catalan had dotz (Cerverí de Girona, c. 1270) and dou (Muntaner, c. 1330); deu is found from a document of 1441.[11] In Roussillon place names have dú, and at Talteüll dúk.[11]
Etymology
The word for the spring is inherited from Old Catalan dou, earlier dotz.[11][3][1] The change from /ow/ to /ew/ is the one that made ⟨crou⟩ into creu and ⟨vou⟩ into veu.[11][3]
The further origin is uncertain.[11][12] The same feminine noun is Old Occitan dotz and, with the article fused to it, adotz; dialects of Franche-Comté and Burgundy have ⟨douis⟩, and Piedmontese has ⟨doss⟩.[11] The REW sets up a Latin feminine *dux (“spring”) beside dux (“leader”), and Wiktionary calls the word pre-Roman, influenced by the Latin noun.[13][1] Coromines rejects the derivation from the Latin noun: the form coincides with the Latin noun and comes close to ductus (“conduit”), but the meanings differ and the Latin words are masculine.[11] He takes it as probably pre-Roman and Indo-European in its structure, perhaps a noun ⟨doukis⟩ or ⟨dūkis⟩, “bubbling of water”, from *dheu-, *dheuk- “to move turbulently, to whirl”, comparing dūkt (“to roar, rage”) and dūkti (“to rage”).[11] Bruguera, the GDLC and Rodamots follow him, Bruguera because the sense and the gender rule out the Latin noun.[12][5][14]
Earliest recorded meaning
Cerverí de Girona, about 1270, rhymes dotz in a poem on the water of baptism and the spring to drink and wash from.[11] Muntaner, about 1330, describes manna rising from a tomb at Ephesus axí con una dou d'aigua ix, as a spring of water flows.[11] Faraudo lists, with a question mark, a dou in Jaume I's Llibre de saviesa (1244).[15]
Semantic evolution
The word means a place where water rises from the ground and the source of a stream.[11][10] The poets of the Renaixença took it up again, Verdaguer among them.[11] It is typical of Eastern Catalan and Roussillon, best rooted in the dioceses of Girona, Vic and Elna, and is not unknown in the rest of the Principality.[11] The old form dou lives on in place names: la Dou de Fontalba near Queralbs, les Dous at Sant Esteve d'en Bas.[11]
Timeline
- c. 1270 – dotz in Cerverí de Girona.[11]
- c. 1330 – dou in Muntaner's chronicle.[11][12]
- 1441 – deu in a document from Banyoles.[11]
