Forms

perigoso (feminine perigosa, masculine plural perigosos, feminine plural perigosas, comparable, comparative mais perigoso, superlative o mais perigoso or perigosíssimo, metaphonic)[1] Old Galician-Portuguese wrote perigoso and perigooso;[2][3] Houaiss also records periigosa and peligroso in the 14th century and perijguoso and prijgossa in the 15th.[2][3]

Etymology

It is inherited from Latin perīculōsus (“dangerous”), written Old Galician-Portuguese perigooso in the oldest texts.[2][4][1] Wiktionary also allows a formation in Galician-Portuguese, from Old Galician-Portuguese perigoo + -oso, or a semi-learned borrowing of the Latin adjective.[1] The Latin word is formed from perīculum (“trial, risk”) with the suffix -ōsus.[5][1] The learned doublet periculoso is a later borrowing of the same word.[1]

The same Latin adjective is Galician perigoso, Spanish peligroso, Catalan perillós, French périlleux and Italian pericoloso.[6][1]

Earliest recorded meaning

The Cantigas de Santa Maria have mui perigosa and perigoosa several times: a man thrown na chama fort' e perigoosa “into the strong and dangerous flame”, a prijon perigoosa, a morte perigoosa, and an illness that was mui perigoosa.[7][3] Cunha and Houaiss date the word to the 13th century.[4][2]

Semantic evolution

The Crónica Troiana calls something maa et perigoosa “bad and dangerous” from beginning to end, and the chronicle of 1344 of aquelle logar tam periigoso “that so dangerous place”.[3][7] Bluteau (1712–1728) defines the word as “risky, in which there is danger of a bad outcome”, and Morais (1813) adds “that puts others in danger, that one cannot deal with safely”.[8][9] Modern dictionaries also record a legal sense, “showing a tendency to commit crime”, and in Portugal a figurative one, “turbulent, reckless” of a person.[10][11] An older sense, “in danger of death”, is now labelled disused.[12][13]
