accurate (English)
Where does "accurate" come from?
The English adjective 'accurate' was borrowed into the language in the 1610s with the now obsolete sense 'done with care', later shifting by the 1650s to mean 'precise, exact'[1]. It derives from the Latin 'accūrātus', meaning 'done with care', which is the perfect passive participle of the Latin verb 'accūrō'[1]. This Latin verb combines 'ad-', meaning 'to, towards, at', with 'cūrō', meaning 'take care'[1]. The root noun 'cūra', meaning 'care', traces back through Proto-Italic to the Proto-Indo-European root '*kʷeys-', meaning 'to heed' or 'to perceive'[3][6]. English also shares a relation with the word 'cure' through these roots[1].
