incūriōsus (feminine incūriōsa, neuter incūriōsum); first/second-declension adjective[1]
Etymology
It is from in- (“not”) and cūriōsus “careful”, or from incūria “carelessness” with -ōsus.[2][1] De Vaan, following Leumann, takes ⟨cūriōsus⟩ as a back-formation from ⟨incūriōsus⟩; he reconstructs cūra as Proto-Italic ⟨*kʷois-ā-⟩ “care, watch”.[3]
Earliest recorded meaning
The OLD's earliest citation is Sallust.[2][4] Köbler dates Sallust 86–34 BC.[4]
Semantic evolution
It meant paying no attention, careless, negligent, unconcerned, indifferent, as in Sallust, Tacitus and Suetonius, and passively neglected, done carelessly, and Lewis & Short call it post-Augustan in most uses.[2][5] nōn incūriōsus was conscientious.[4]
British Medieval Latin used it for careless and not interested in.[6]
