Etymology

It is borrowed from Latin assessor (“one who sits beside; assistant, adviser”), a learned word.[2][3][4][1] The Latin noun is formed on the participle of assideō (“to sit beside”), itself made of ad- and sedeō (“to sit”).[2][5][1] French borrowed the same word in the 13th century as French assesseur.[6]

The dictionaries date it very differently: the DCECH to 1592, the BDELC to 1495 and the DTME to 1331.[2][3][7] The DEMel has an earlier record of 1279.[8]

Earliest recorded meaning

The DEMel's earliest primary record of asesor is a document of 1279 from the Longares charter collection, and its vocabulary of the Vidal Mayor (c. 1250) also lists the word.[8] The Cancionero de Baena (c. 1370–1424) spells it açessor.[8] From the start it was a legal word: Covarrubias in 1611 defined it as the man who sits together with the judge to try and sentence certain cases.[9]

Semantic evolution

The Academy's 1770 dictionary defined it as the lawyer who sits with a lay judge to rule and pass sentence, and its 1843 edition added the wider sense “one who gives another advice”.[10][11] In 1884 the Academy gave the etymology and, by extension, made the word an adjective for anyone who advises another with his opinion.[12] Today it is chiefly a professional adviser, a consultant, as in asesor fiscal “tax adviser”.[13][14] The verb asesorar is recorded from 1770 in the BDELC but only from about 1800 in the DCECH, and asesoría from 1620.[3][2] In Chile asesor del hogar is a euphemism for a domestic employee.[15]
