Pronunciation

Forms

curioso (feminine curiosa, masculine plural curiosi, feminine plural curiose)[1]

Etymology

It is a learned word, borrowed from Latin cūriōsus (“careful; inquisitive”), from cūra (“care, concern”).[2][3][4][1] The Latin adjective first meant “one who takes care of something”, and, from there “eager to know”; the sense “strange” is documented in Latin from the 9th century and lives on in southern dialects.[2][5] The same borrowing is French curieux and Spanish curioso.[3][5]

The Oxford Latin Dictionary analyses the Latin word as cūra with the suffix -ōsus, while Wiktionary takes it as a back-formation from incūriōsus (“careless”), and Devoto from an intermediate ⟨*curius⟩.[6][1][7] De Vaan traces cūra to Proto-Italic ⟨*kwois-ā-⟩ “care, watch” and the Proto-Indo-European root *kʷeys- (“to heed”).[8]

Earliest recorded meaning

The TLIO's first record is the Sienese translation of Giles of Rome, of 1288, and Bono Giamboni uses the word before 1292; in these early texts curioso means “careful, attentive”.[9][2] The sense “eager to know” is in Petrarch, before 1374.[2][10]

Semantic evolution

Old Italian used the adjective for something done with care, for a person refined in dress and food, for one greedy for something, and for one full of worries, as well as for one eager to see and learn.[9] The desire to know easily turned into prying: a life of Saint Anthony calls a man vano uomo, e curiosissimo delle mondane novitadi “a vain man, and most curious about worldly news”.[11]

The sense “odd, unusual, arousing curiosity” is recorded about 1535, in Annibal Caro.[2] The noun curiosità goes back to Bono Giamboni before 1292, and took the sense “rare object” in Galileo; the verb curiosare, to poke about, appears in Ippolito Nievo before 1861.[2] English borrowed the noun curioso in 1658–1672 for a person curious about science and art, and later a connoisseur.[10]
