하다
hada[ha̠da̠]
The English phrase "to do" is translated into Korean as 하다 (hada).
하다 means to perform an action or carry out a task. It is frequently attached to nouns to turn them into verbs, such as turning the noun 공부 (study) into 공부하다 (to study). Additionally, 하다 can be used to describe someone's feelings or states, such as turning the adjective 덥다 (to be hot) into 더워하다 (to be hot) or 슬프다 (to be sad) into 슬퍼하다 (to be sad).
Which one should you use?
While 하다 is the general term for "to do", you may use 실행하다 to mean "to execute" or "to carry out" and 시행하다 to emphasize the act of performing or doing in a formal context.
How does it change in a sentence?
The verb 하다 changes based on the level of politeness and formality required: 해 is the casual, non-honorific form, 해요 is the polite, standard form and 합니다 is the formal, polite form.
