Forms

cūriōsē (comparative cūriōsius, superlative cūriōsissimē)[1]

Etymology

It is from Latin cūriōsus (“careful; curious”) + -ē.[1][2][3] The adjective is formed from cūra (“care, anxiety”), whose further origin de Vaan finds uncertain; he considers Proto-Italic *kwois-ā- (“care, watch”) and a link with Proto-Indo-European *kwei-s- (“to heed”).[4]

Earliest recorded meaning

Köbler dates it from Cicero,[3] who writes in the Brutus conquiram ista posthac curiosius, “I will look into these things more carefully later”.[1][5]

Semantic evolution

Its first sense is carefully or attentively: Vitruvius has things arranged carefully and precisely, Celsus wrapping someone carefully in clothes, and Pliny the Younger a letter written with more care.[1][6] It could also mean elaborately: Quintilian speaks of people who talk elaborately rather than in good Latin, and Apuleius of ceilings carefully hollowed out in citrus wood and ivory.[1][5]

The second sense is inquisitively: Cicero says that those who ask what he himself thinks on every question are more curious than they need be.[1][6] Gellius and Apuleius use it the same way.[1] In British Medieval Latin it means carefully, from Bede on, elaborately, and in an extravagant style.[7]
