Forms

especioso (feminine especiosa, masculine plural especiosos, feminine plural especiosas, metaphonic)[1] Houaiss records specioso in the 15th century and especioso in 1657.[2]

Etymology

It is borrowed from Latin speciōsus (“good-looking, beautiful”), formed from speciēs (“appearance”) with the suffix -ōsus.[2][3][1][4] Nascentes takes it by a semi-learned route.[5] Already in Latin the adjective meant both “of fine appearance” and “having only the appearance of truth”, since the noun, set against rēs (“the real thing”), could mean a pretext.[6]

The same Latin word is Spanish especioso, Italian specioso, Romanian specios and French spécieux;[1][6] French borrowed it about 1370.[1][6]

Earliest recorded meaning

Houaiss records the word in the 15th century, spelt specioso; the spelling especioso follows in 1657, and Cunha places the word in the 17th century with the sense “deceptive in appearance”.[2][3]

Semantic evolution

Caldas Aulete quotes Arrais for the forma especiosa of a maiden, and Padre António Vieira for especiosas lágrimas, “tender, heartfelt tears”.[7] Morais (1813) defines it as “of good appearance, coloured”, as of reasons, motives and pretexts.[8] Vieira's dictionary (1871) gives “beautiful, perfect” and “having good appearances”, quoting o pretexto especioso de Religião “the specious pretext of religion”.[9] Figueiredo (1899) lists “of good appearance”, “illusory”, “misleading under an appearance of truth” and “beautiful”.[10] Today the sense “deceptive, specious” comes first, and “beautiful, attractive” is literary.[2][11][12]

Timeline

  • 15th century – first record, spelt specioso.[2]

  • 1899 – Figueiredo lists the illusory and the beautiful senses side by side.[10]
