In an open, obvious, or publicly revealed manner, without attempting to hide something.
From 'overt' (from Old French 'ouvert,' past participle of 'ouvrir,' to open, from Latin 'operire'). The adverb form emerged in the 16th century.
The legal concept of 'overt acts' distinguishes between thinking about a crime and actually doing it—simply planning a robbery isn't a crime, but an overt act like buying supplies for it can be prosecuted.
