overt

The word 'overt' entered English in the early 14th century from the Old French adjective 'overt', meaning "open, open-handed, generous," which was the past participle of the verb 'ovrir' (to open). This Old French term descended from the Latin 'apertus', the past participle of 'aperire' (to open, uncover, reveal). The literal sense of "open to view" was carried directly from French into English legal and general vocabulary. The modern meaning retains this core idea of openness, describing actions or qualities that are not hidden or secret but are publicly observable and manifest.

Structure: over (over, above) + t (past participle suffix) 'over' is from Old English 'ofer', meaning "above, beyond, across." The '-t' is a vestigial past participle suffix from Old French, related to Latin '-tus'.
