게 다듬다

polish it into better shape

다듬다 is trimming something into better shape — a recipe perfected over generations, a figure smoothed by massage, a rough draft tidied up. Half these lines are about language: taking a borrowed or clumsy word and reworking it into plain Korean. The -게 slot names what you are aiming at: 예쁘게 (neatly), 매끄럽게 (smoothly), 쉽게 (into something easy).
