웃다
utda · TOPIK 1
to laugh, to smile
😄 웃다 = 웃 (laugh) + 다 (verb ending); 웃 sounds like oot, a hoot of laughter
The stem 웃 is said like oot, close to hoot, and a hoot is a burst of laughter. 다 is the dictionary ending on every Korean verb. The same stem gives 웃음 (laughter, a smile) and 웃기다 (to be funny).
