Common Mistakes

Incorrect: 먹아요 → Correct: 먹어요. The stem 먹- ends in a dark vowel (ㅓ), so it takes -어요 not -아요. Match the vowel harmony.

Incorrect: 있어요 친구는 책을 열 수 → Correct: 친구는 책을 열 수 있어요. Korean uses Subject-Object-Verb (SOV) order. The verb must come at the end of the sentence, unlike English where it comes after the subject.
