Pronunciation

Forms

rasar (first-person singular present raso, first-person singular preterite rasé, past participle rasado)[1]

Etymology

It is formed from Spanish raso + -ar, according to the DLE, Moliner and García de Diego.[2][3][4] Corominas lists it among the derivatives of raer, beside the adjective, which continues Latin rāsus (“scraped, shaved”), the past participle of rādō (“to scrape, shave”).[5][6]

Wiktionary and the REW instead trace the verb to *rāsāre (“to shave”), a Latin verb formed on that participle, which is also the source of Italian rasare, French raser, Catalan rasar and Portuguese rasar.[1][7] Covarrubias in 1611 already derived it from the supine of the Latin verb.[8]

The Latin verb goes back to Proto-Italic *rasd-e/o-, and de Vaan compares Welsh rhathu (“to scrape, shave”).[9]

Earliest recorded meaning

The CDH's first record is in the Libro de Alexandre (1240–1250, in an early 15th-century copy), where the moat of a city is deep and de agua bien rasada “brimful of water”.[10][11] In Alfonso X's General estoria (c. 1275) a man's eyes rasaron … de agua “filled with tears”.[10] Corominas and the BDELC date the verb only from Nebrija, 1495.[5][6]

Semantic evolution

Nebrija records rasar la medida, Latin hostio, “to strike off a measure of grain”, and the noun rasadura.[5][12] Covarrubias explains rasar as a vessel being full to the brim, levelled with the rasero, the round stick used to strike off dry measures.[8] Autoridades gives this sense and a second one, “to pass lightly grazing another body”.[13] Corominas notes that rasar was used earlier with the sense of arrasar “to raze”, and in 1558 a text from La Paz says that many woods han rasado “have been cleared”.[5][14] The DLE keeps that sense as little used.[2]

Salvá in 1846 records the phrase rasarse los ojos de agua o lágrimas “for the eyes to fill with tears”, which is still found in Mexico in 1945.[15][14] The Academy gave the etymology de raso from 1884.[16] In Andalusia a horse rasa when its incisors become level, at about eight years.[17]
