How Korean verbs conjugate

Every form starts from the stem, which is the dictionary form without 다. For a regular verb the polite present depends on the stem's last vowel: ㅏ or ㅗ take 아요, and everything else takes 어요, so 먹다 becomes 먹어요 and 앉다 becomes 앉아요.

The verbs ending in 하다, which is more than half of them, all become 해요. The rest of the irregular patterns are small families that bend a sound before a vowel, like 듣다 becoming 들어요. The guide to Korean verb conjugation walks through the rules, and every verb below has a page showing how its forms are built.
