Grammar note (르 irregular): 르-irregular verbs and adjectives end in 르다. Before the -어/-아 suffix the 르 splits: the ㅡ vowel drops and a ㄹ is added as the final consonant of the preceding syllable. 모르다 (not to know) → 몰라요 (not *모르어요), 부르다 (to call) → 불러요. Before consonant suffixes 르 stays intact: 모르고, 부르지. See all 르-irregular verbs →
