Forms

rasero m (plural raseros)[1]

Etymology

It is inherited from Vulgar Latin rasorium, through an earlier Old Spanish *rasuero.[2][3][4][1] Corominas calls the change a regular development, and notes that Latin has the word only in glosses, as an adjective.[2] Wiktionary gives Late Latin rāsōrium, recorded from the 5th century and formed from rādō (“to scrape, shave”) with the tool suffix -tōrium.[1] The Academy's dictionaries of 1884 to 1917 derived it from the verb rasar.[5][6]

The same Latin word gave Italian rasoio, French rasoir, Occitan rasor and Catalan raor, all meaning “razor”, and the Catalan rasor “strickle”.[2][7][8] Corominas suggests that the feminine is hidden in the name of the Castilian judge Nuño Rasura, written ⟨Rasuera⟩ in archaic texts, and survives as rasera.[2]

Earliest recorded meaning

The first records in the CDH date from the 1450s: Pedro Marín's sermons (after 1455) speak of a full measure raýda con su rasero “levelled with its strickle”, and Fernando de la Torre's letters (before 1456) already use the word figuratively, for a standard of judgement.[9] Corominas and the BDELC date it from Alfonso de Palencia's Vocabulario of 1490.[2][3]

Semantic evolution

The phrase por un rasero “with exactly the same measure, without distinction” is recorded from the late 15th century: in Juan del Encina the strong and the weak todos van por un rasero in death.[9] In the Americas it appears from 1528 (Río de la Plata): a sickly land que a todos los llebó por un rasero.[10] The Diccionario de Autoridades described the tool as a round stick, blunt at both ends, used to strike off a measure of grain, and gave the figurative sense of strict equality.[11] Modern Spanish uses the word for any standard of judgement, as in doble rasero “double standard”.[12][1] In Leonese it is also a carpenter's tool for shaping handles.[13]
