게 쉬다

rest a certain way; also breathe

쉬다 is resting or taking time off, and 편하게/편안하게 쉬다 "rest comfortably" is the commonest phrase here, in three lines. Other adverbs sharpen it: 철저하게 쉬다 "rest properly, with intent", 깔끔하게 쉬다. The same verb also means to breathe, and one line uses it that way about haenyeo divers — 숨을 되게 특이하게 쉬다. Which sense is meant is settled by whether 숨 "breath" appears in the sentence.
