눈뜨다 conjugation (nuntteuda, to open one's eyes)

To say to open one's eyes politely in the present tense, use 눈떠요 (noon-ttuh-yoh) · nuntteoyo. Below is the full conjugation of 눈뜨다 across the three tenses and three everyday speech levels.

Grammar note (으 irregular): 으-irregular verbs end in ㅡ preceded by a consonant (e.g. 쓰다, 예쁘다). Before a vowel suffix, the ㅡ is dropped entirely. 쓰다 (to write) → 써요, 예쁘다 (to be pretty) → 예뻐요. Because ㅡ itself has no inherent "brighter" or "darker" quality, the vowel harmony is determined by the preceding syllable. See all 으-irregular verbs →
