Forms

gastar (first-person singular present gasto, first-person singular preterite gasté, past participle gastado)[1]

Etymology

It is inherited from Latin vastāre (“to lay waste, devastate”), pronounced *wastare in late Latin under the influence of a West Germanic verb, the source of Old High German wuostan and German wüsten (“to lay waste”).[2][3][4] Wiktionary names the Germanic verb as Frankish *wōstijan.[1] The Germanic /w/ was strengthened to /gw/, as in guerra and guardar, and in this verb /gw/ was then reduced to /g/ in the unstressed first syllable, as in galardón.[5][2][1]

The same verb is Portuguese gastar, Catalan gastar, French gâter and Italian guastare.[6][7] Gamillscheg seems to have taken the Spanish verb for a Gallicism, since the Germanic verb is attested only in West Germanic and so would be Frankish rather than Gothic.[2] Corominas rejects this: the Italian verb shows that the Germanic influence acted on Vulgar Latin, medieval Catalan has the native guastar, and the form with /w/ in the Mozarabic of the Cordoban poet Ibn Quzman proves the word native in the south of Spain.[2][8]

The Latin verb is formed from vāstus (“empty, desolate”).[9] De Vaan traces it to Proto-Italic *wāsto- and Proto-Indo-European *h₁u(e)h₂-sto-, with the cognates Old Irish fás (“empty”) and Proto-Germanic *wōsti- (“empty, barren”).[10] The learned devastar and vasto come from the same Latin words.[3]

Earliest recorded meaning

The Aragonese Liber Regum, of the first years of the 13th century, uses the verb in its old sense “to lay waste”: „passoron mar e uinieron gastando por tierra de Roma” “they crossed the sea and came laying waste the land of Rome”.[2][11] The Fazienda de Ultra Mar (c. 1200, in a 13th-century copy) has the sense “to consume”: „Agora gastara aquella gent nuestra tierra cumo gasta el buey la yerba del campo” “now that people will eat up our land as the ox eats up the grass of the field”.[11] Earlier still, in the first half of the 12th century, Ibn Quzman uses a Mozarabic participle of the verb for “squandered”.[2]

Semantic evolution

The noun gasto and gastador already have the modern sense of spending in Berceo, and the verb has it in the glossaries of Toledo and the Escorial of about 1400.[2][3] The older and wider senses remained: Nebrija glosses gastar e destruir, and in the Quijote the verb often means “to waste, spoil”, as of time or of a woman's complexion.[2] For Corominas this makes it unlikely that the same use in Juan de Valdés is an Italianism.[2]

Covarrubias in 1611 explains the military gastadores as the sappers who dig trenches and haul stone and fascines, and lists phrases such as wasting time in vain.[12] In 1817 the Academy still gave “to lay waste a province”, “to digest” and “to spoil”; in 1884 it added “to have habitually” (a mood), “to own, use, wear” (a car, glasses, a beard) and gastarlas “to behave”.[13][14] The DLE now marks “to lay waste” and “to digest” as obsolete.[4]

In Argentina gastar is to tease or make fun of someone, and in Colombia and Paraguay to treat someone to food or drink.[15] In Judeo-Spanish gastarse is also said of meat and fish that go bad.[16]
