Forms
peligroso (feminine peligrosa, masculine plural peligrosos, feminine plural peligrosas)[1] Old Spanish had perigloso, periglosa, peligloso and perillosa beside peligroso.[2][3]
Etymology
It continues inherited from Old Spanish perigloso, inherited from Latin perīculōsus (“dangerous”), a semi-learned word like peligro.[1][4][2][5] Corominas lists it among the derivatives of that noun, and Wiktionary allows either analysis: the noun plus the suffix -oso, or a semi-learned borrowing of the Latin adjective.[2][1] The Latin adjective is formed on perīculum (“trial, risk, danger”) with -ōsus.[6][1] The noun comes from the same root as perītus (“experienced”) and experior (“to try”);[2][5] Wiktionary connects it, with doubts, with Proto-Indo-European *perh₃- (“to go through, attempt”).[1]
The modern form arose by metathesis of the liquids.[1] Following Cuervo, Corominas notes that by Grammont's laws this change is explained in the derivatives, the verb peligrar and this adjective, rather than in the noun; he adds that early Castilian disliked the groups ⟨gl⟩ and ⟨cl⟩, which gave perigro, then the modern noun by dissimilation.[2]
The same Latin word is Portuguese perigoso, Galician perigoso, Asturian peligrosu, Catalan perillós, French périlleux (from perilleus), Italian pericoloso and English perilous.[7][8][9][10][1] Old Portuguese had perigoso and perigoosa in the 13th century and peligroso in the 14th.[11]
Earliest recorded meaning
Corominas's first record is perigloso in Berceo's Milagros de Nuestra Señora (317c).[2][5] Cabrera quotes another line of the Milagros: Essa salvo a Peidro enna mar periglosa “she saved Peter on the perilous sea”.[12] In Alfonso X's Lapidario (1250–1279) a stone is found far from settlements in places peligrosos for lack of water and for venomous animals.[13]
Semantic evolution
Nebrija renders the word by Latin periculosus and periclitans.[14] Autoridades defines it as “having risk or able to cause harm”, and figuratively as said of a turbulent, reckless person; it cites Covarrubias for the sense “one who is in danger of death”.[15] That passive sense appears in the Americas: in Puebla in 1572 a pregnant woman with a pain in her side has been muy peligrosa “in great danger”, and in Bogotá in 1588 a man is enfermo y muy peligroso.[16] The Academy kept the figurative sense for people, and the DLE now defines it as a person who may cause harm or commit crimes.[17][4]
