The clearest lines here show the piece that flips an action onto the thing it happens to: from the verb meaning to slice you get 썰리다, meaning to be sliced, which is what the lines about it cutting so easily and about being thinly sliced are using. It also sits inside 쫄리다, meaning to feel on edge, in two more lines. Korean has several of these passive pieces, 이, 히, 기 and 리, and which verb takes which simply has to be learnt. The remaining lines are false matches on unrelated words.
