From the same root
Forms
raiz f (plural raízes)[1] Medieval texts write raiz, rayz and rays, and in the 14th century also rrayz, reyz and rreyz.[2][3]
Etymology
It is inherited from Latin rādīx (“root”), written Old Galician-Portuguese raiz in the oldest texts.[2][3][1] The earliest form Houaiss records, ⟨radize⟩ in a document of 1091, still has the Latin ⟨d⟩ between vowels, which the 13th-century form has lost.[2] Old Spanish shows the same pair: Berceo has Old Spanish raíz beside the older radiz.[4]
The same Latin word is Galician raíz, Spanish raíz, Catalan rel, Italian radice and Old French raïz, which survives in French only in the compound French raifort “horseradish”.[5][6][4]
The Latin word goes back to *wrādīks, from Proto-Indo-European *wréh₂ds.[1] De Vaan compares Welsh gwraidd (“roots”), Gothic 𐍅𐌰𐌿𐍂𐍄𐍃 (waurts) and Old English wyrt, and thinks the ⟨-d-⟩ of the root was probably a suffix.[7]
Earliest recorded meaning
The Cantigas de Santa Maria of the 13th century use raiz for the roots of plants, in a line about a cure that works nen con raizes nen frores “neither with roots nor with flowers”, and figuratively in rayz de Jesse, the root of Jesse; the phrase de raiz there means “from the very start”.[8]
Semantic evolution
The figurative sense “origin, cause” is old: Houaiss dates it to the 14th century.[2] A cantiga already opposes movil e raiz, movable and immovable goods, and Morais (1813) records bens de raiz “real estate” as opposed to movable property, a sense Houaiss still lists.[9][10][2]
Later centuries added technical senses: the root of a tooth, a hair or a nerve, the root of a word in grammar and of a number in mathematics.[2][11] In the plural the word also means the ties with the place where one grew up.[2][1] Recent Brazilian slang uses raiz as an adjective for something traditional or authentic.[1][12]
The word passed into the Portuguese-based creoles: Kabuverdianu raìs, Guinea-Bissau Creole rais and Papiamentu rais.[1]
