죠

right? — polite shared-knowledge ending

A squeezed form of 지요 that ends a sentence by treating the content as something the listener already knows or will agree with, so it usually translates as right?, of course, or isn't it. 그렇죠 "right, exactly" is its most common shape by far and works as pure agreement. 전 좋죠 "I'd love it, obviously" shows the confident-statement use, and 나중에 얘기하시죠 "let's talk later" shows it softening a suggestion. Drop the 요 and you get 지, the same move in casual speech.

Register: polite spoken, very frequent
