Synonymous with 수술칼
"Onder het mes gaan" is a dutch saying for "to go under the knife".
As in 'not heavy' or is it a light color?
As in not heavy, the opposite is 무겁다 (/무겁습니다/무거운/무거워)
Is there a Hanja equivalent for 가볍 here and 무겁 as in 무겁다?
Only 하다 adjectives have hanja
Yeah, I know, I just asked because 무 in 무겁다 looks a lot like (sounds the same as) the 무 in 무료 which does have a Hanja equivalent (無 i.e. 없을 무). It would make a lot of sense that way.
