This adjective relates to the marketplace (agora)—either the place itself, the activities there, or the people who frequent it. In Acts 17:5, it describes the 'marketplace loungers' or common rabble whom the Jews recruited to create a riot in Thessalonica—people hanging around the agora with time on their hands. In Acts 19:38, the town clerk refers to 'court days' (literally 'marketplaces are being held'), the regular sessions when courts convened for legal business. The word thus spans physical location, judicial proceedings, and social class—all connected to the marketplace as the civic and commercial center.
