어 풀다

undo, loosen, release, whisk

풀다 undoes anything tied, tight, held, or lumpy: a leash, a stiff shoulder, an egg beaten smooth, money pushed into an economy, feelings kept inside. What comes before with -아/어 usually says how — 어깨와 목을 주물러 풀어주시거나 'knead the shoulders and neck loose', 과거 정권들이 전부 다 돈을 찍어 풀었어 'past governments printed money and pushed it out'. The bare command 풀어! covers cooking, driving and letting an animal off its lead in these lines alike.
