Forms

especioso (feminine especiosa, masculine plural especiosos, feminine plural especiosas)[1]

Etymology

It is borrowed from Latin speciōsus (“beautiful, good-looking”), a learned word.[2][3][4][1] Corominas explains the Latin adjective from the sense “fine appearance” that its base speciēs also had.[2][3] The noun meant “sight, look, appearance”, and so the Latin adjective could also mean “showy” and “deceptive in appearance”.[5][6][7]

The same Latin word gave French spécieux, Italian specioso and Portuguese especioso.[1][6][8] Corominas notes an isolated earlier instance in Berceo with the sense “calm”; the Tentative Dictionary suggests that one medieval instance is a slip for espacioso.[2][9]

Earliest recorded meaning

Corominas dates the word from 1639, in Luis Muñoz.[2][3] The Diccionario de Autoridades quotes Muñoz's life of Fray Luis de Granada for the sense “exquisite, carefully wrought”: ricas y preciosas, especiosas, y superiores à las cosas terrénas “rich and precious, exquisite, and above earthly things”.[10]

Semantic evolution

Autoridades gave two senses, “exquisite, perfectly done” and “apparent, coloured, dressed up with deceit”, quoting Saavedra Fajardo on the fine names with which the Romans disguised their tyranny.[10] From 1817 the Academy defined it as “beautiful, precious, perfect” and, figuratively, “apparent, deceptive”, and the two senses still stand in the current dictionary.[11][4] The deceptive sense now prevails: Moliner labels it learned, and Vox defines the word only as “seemingly logical but deceptive”.[12][13] In the Americas it is recorded from 1794 in Lima and Bogotá, already in phrases such as especioso pretexto.[14]

Timeline

  • 1491 – the Old Spanish Textual Archive has the word in Diego de San Pedro's Arnalte y Lucenda, printed in Burgos.[15]
  • 1639 – Corominas's first record, in Luis Muñoz.[2][3]
  • 1732 – the Diccionario de Autoridades records the senses “exquisite” and “deceptive”.[10]
  • 1794 – first records in the Americas, in Lima and Bogotá.[14]
  • 1884 – the Academy's dictionary first gives the etymology from Latin.[16]

Meanings

Adjective

  1. (dated) beautiful, precious, perfect.[4][12]
  2. specious: apparently sound but deceptive: Nos dio una excusa especiosa para no venir.[4][13][1]
