Pronunciation

  • /reˈɡaɾ/, [reˈɣ̞aɾ][1]

Forms

regar (first-person singular present riego, first-person singular preterite regué, past participle regado)[1] Old Spanish also wrote rregar and arregar.[2] The present has the diphthong /je/ (riego, riega) as early as Juan Ruiz, beside an older Aragonese rego.[3]

Etymology

It is inherited from Latin rigō (“to water, to wet”).[3][4][5][1] The same Latin verb gave Portuguese regar, Galician regar and Catalan regar, and Old French reer.[6][7]

De Vaan notes that the compound irrigō (“to lead water onto, irrigate”) is older than the simple verb, which he traces to Proto-Italic *rig-ā- (“to lead toward”).[8] He finds the likeliest source in Proto-Indo-European *Hriǵ- (“to stretch”), the root of rigeō (“to be stiff”), which explains the ⟨i⟩ best; a connection with regō (“to lead”), “to lead water onto the fields”, is the other proposal he discusses.[8][1]

Since a short Latin /i/ gives Spanish /e/, which does not diphthongise, the present should have kept /e/, and Corominas explains its diphthong as analogy with verbs such as fregar and plegar.[3] He adds that the noun Old Spanish riego (“stream, furrow”), found in Berceo, helped the change: that word is of pre-Roman origin, probably related to Basque erreka (“stream”), and had a short /e/.[3][4]

Earliest recorded meaning

Corominas first finds the verb in charters of 1161 and 1200 in Oelschläger's list.[3][4] DEMel has earlier records, in Navarrese documents of 1157 and in a document of 1160.[2] The first context in the CDH is the Fuero de Zorita (1218–1250), which renders Latin aquam ad rigandum as agua pora regar “water for irrigating”.[9]

Semantic evolution

In Alfonso X's prose the verb already means both sprinkling water on something and the supply of water by a river or canal to the land it crosses.[10] The Diccionario de Autoridades gives four senses: watering the land and its plants, sprinkling rooms and streets to settle the dust, raining (of clouds) and flowing through a region (of rivers).[11] The Academy added the beekeepers' sense, of bees moistening the cells that hold the brood, in 1817.[12]

Corominas notes a modern construction with the scattered liquid or thing as the object (regar lágrimas, regar flores), which the Academy still lacked in 1884.[3] In Colombia and Ecuador the verb came to mean “to spill, knock down, scatter, sow”, a usage Alemany called a barbarism in 1917.[13] Today in much of Spanish America it also means to spread news or gossip, and in several countries, as a pronominal verb, to spread out over a wide area.[14][5] It is also used of washing down a meal with wine or another drink.[15]

  • 1564 – first record in the Americas, in Mexico.[17]
  • 1591 – Percyvall translates it “to water”.[18]
  • 1611 – Covarrubias defines it as pouring water on the earth.[19]
