Forms

raíz f (plural raíces)[1] Old Spanish texts mostly write rayz, also raiz, rrayz, rrays and the plural rayzes.[2] Berceo still has the older form radiz once, beside raíz.[3] The stress ráiz (and réiz) is found in some Spanish writers of the 17th–19th centuries and is widespread in popular speech in the Americas.[3]

Etymology

It is inherited from Old Spanish rayz, inherited from Latin rādīx (“root”).[3][4][5][1] Berceo uses the modern form but in one poem still the older form radiz.[3]

The Latin word is inherited by all the Western Romance languages: Portuguese raiz, Galician raíz, Asturian raíz, Aragonese radiz, Catalan rel, Occitan raitz, Old French raïz and Italian radice.[3][6][1] Catalan now says arrel, with the ⟨a⟩ of the feminine article fused to the noun.[7] The Old French word was replaced by French racine and survives only in the compound raifort “horseradish”.[3][8]

The Latin noun goes back to Proto-Italic *wrādīks and Proto-Indo-European *wréh₂ds.[1] De Vaan reconstructs the Proto-Indo-European word as *ur(e)h₂-d-iH- “root”, and compares Welsh gwraidd “roots”, Ancient Greek ῥάδιξ (rhádix, “branch, twig”), Old English wyrt and Old Norse rót.[9] The English word radish has the same Latin source.[1] Corominas calls Ancient Greek ῥίζα (rhíza, “root”), from which the learned rizoma was formed, a synonym of the Latin word and related to it.[3][4]

Earliest recorded meaning

Corominas dates the word to a charter of 1207 and to Berceo.[3][4] The Fazienda de Ultra Mar, dated c. 1200 and known from a 13th-century copy, has it in the sense “root of a tree”: A la rayz daquel arbor estava Abraam “Abraham stood at the foot of that tree”.[10] Already in the Fuero de Zorita (1218–c. 1250) it also means landed property: Que ninguno non pueda uender rayz alos freyres “that no one may sell land to the friars”.[10]

Semantic evolution

In the prose of Alfonso X the word means the root of a plant, landed property (muebles & rayzes “movable goods and land”), the lower part of a thing and the origin from which something comes.[11] The plural raízes for real estate, as opposed to movable goods, is in Juan Ruiz, and Nebrija has bienes raízes.[3] Records from the Americas start in 1535, when edible roots of Santo Domingo are compared with melons.[12]

The figurative senses “hidden part from which the visible part comes”, “foot of a thing” and “origin” are in the Academy's 19th-century dictionaries, which also define a farm, a vineyard or a house as raíz.[13] Salvá adds the arithmetical sense, the number that multiplied by itself gives a quantity.[14] The Academy gave the Latin etymology and a botanical definition in 1899.[15] Today the word is also the lexical morpheme of a family of words in grammar and the root of an equation in mathematics.[5] In the interior of Mexico raíz alone meant the sweet potato.[16]
