"Are you wearing a ring?"
Yeah, there are many words for "to wear" in Korean.
입다: to wear - usually for clothes (옷을 입다, 바지를 입다...)
끼다: to wear / to fit on - for gloves, rings (장갑을 끼다, 반지를 끼다)
차다: to wear / to put on - for belts, and accesories (허리띠를 차다, 손목시계를 차다, 귀걸이를 차다)
매다: to wear - exclusive to tie (넥타이를 매다)
I'm probably forgetting somethings though, so don't take it for granted.
