Busybodied

Characterized by the behavior or qualities of a busybody; being overly interested in other people's affairs, meddlesome, or intrusive.

Derived from 'busybody' (a noun meaning a person who meddles) with adjectival suffix '-ed,' meaning 'having the quality of or characterized by busybody behavior'; the base 'busybody' comes from 'busy' + 'body' (meaning a person).
