열다

to open
🚪🔑 yeolda: YAWL the door open — yeol- is the open part, -da marks a verb
The stem 열 (yeol) carries the meaning open; 다 (da) is the dictionary ending on every Korean verb. Yeol sounds close to yawl or y'all: Y'all, open up! The same stem appears in 열쇠 (yeolsoe), key — literally the open-metal.
