Forms

pericoloso (feminine pericolosa, masculine plural pericolosi, feminine plural pericolose, superlative pericolosissimo)[1]

Etymology

It is a learned word, borrowed from Latin perīculōsus (“dangerous”), from perīculum (“trial, attempt; risk, danger”) and the suffix -ōsus.[2][3][4][1] Wiktionary considers it probably a semi-learned borrowing;[1][2] Italian pericolo is also learned.[1][2] Old and dialect forms are Old Italian periculoso, perigoloso, piricoloso and the Tuscan pricoloso, and Körting gives periglioso beside it.[5][6]

The Latin adjective has outcomes throughout Romance: Romanian periculos, Old Occitan perilhos, French périlleux, Catalan perillós, Spanish peligroso and Portuguese perigoso.[6] The Latin noun first meant “a trial, experiment” and comes from a verb *perīrī (“to try”), seen in perītus (“experienced”) and experior (“to try, test”).[2][3]

Earliest recorded meaning

The first record is periculoso in Guittone d'Arezzo, before 1294, writing of earthly greatness, “come è affannosa e periculosa ad acquistare” (how wearisome and dangerous to acquire).[2][7] Zingarelli dates the word to about 1261.[8] The form pericoloso is in Dino Compagni (1310–1312).[2]

Semantic evolution

At first the word meant “full of risks”; of a person or thing that can do harm it is recorded about 1304 in Giordano da Pisa.[2] Dante has the superlative in the Convivio: “pericolosissima negligenza”.[7] In the 20th century it entered law and sport: pericolosità (criminal dangerousness) is first recorded in 1912, and gioco pericoloso, a foul in football, in 1970.[2] A regional modern use, “reckless, daredevil”, is in the GDLI's supplement.[5]
