To say to help, to serve, to benefit politely in the present tense, use 위해요 (wee-hae-yoh) · wihaeyo. Below is the full conjugation of 위하다 across the three tenses and three everyday speech levels.
Grammar note (하다 verb): 하다 verbs are formed with a Sino-Korean noun + 하다 (e.g. 공부하다 = study + do). 하다 conjugates irregularly: the ㅏ in 하 contracts with the -아/-어 suffix to give 해 (not *하어). Present polite: 해요; past polite: 했어요. The formal ending is 합니다 (not *하습니다). Most noun+하다 compounds follow this pattern uniformly. See all 하다 verbs →
