Forms

escamoso (feminine escamosa, masculine plural escamosos, feminine plural escamosas, metaphonic)[1]

Etymology

It is borrowed from Latin squāmōsus (“covered with scales”), according to Houaiss, Cunha, Nascentes, Aurélio and the DLP.[2][3][4][5] The Latin adjective, already in Plautus, is formed on squāma (“scale”) with the suffix -ōsus.[6] Vieira, Michaelis and DELPo instead form it in Portuguese from escama and -oso,[7][8][9] and Wiktionary allows both.[1]

The same Latin word is Spanish escamoso, Italian squamoso and Romanian scămos.[10][11]

Earliest recorded meaning

Cunha dates the adjective to the 16th century, and Houaiss to 1611.[3][2] Bluteau quotes it from the epic Ulyssea of Gabriel Pereira de Castro, of the scaly horses that draw Neptune's chariot (Escamosos cavallos).[12]

Semantic evolution

Bluteau already has ossos escamosos as a term of anatomy,[12] and the modern dictionaries keep that use for a bone of the skull, beside the botanical sense “bearing scales”.[13][8] In Brazilian informal speech, Houaiss labels it as from São Paulo, the word has come to describe an unpleasant, unsociable person.[2][13][5]

Timeline

  • 16th century – Cunha's first date.[3]
  • 1611 – Houaiss's first date.[2]
  • 1712–1728 – Bluteau quotes escamosos cavallos and lists ossos escamosos.[12]
  • 1871–1874 – Vieira derives it from escama with the suffix -oso.[7]
