Resembling or characteristic of a court; having the refined manners or elaborate style typical of a royal court.
From 'court' + '-y' (adjective suffix), creating an informal descriptor for things that seem courtly or court-like in nature or appearance.
While 'courtly' is the proper adjective, 'courty' emerged as playful slang to describe anyone trying too hard to seem fancy or sophisticated—it's the word people use mockingly.
