Korean verbs come in many forms. To conjugate them you must start with the 'dictionary form', which will always end in -다. Like so:

• 가다 to go
• 먹다 to eat
• 자다 to sleep
• 오다 to come
• 미안하다 to be sorry

To conjugate a verb, first, drop the -다. This will give you the verb stem, like so:

Now you must replace the -다 with either -어요, -아요, or just plain 요. The choice depends on the verb stem. If it ends in

Exceptions are made for 하다, which conjugates as 해요, and for verbs which end in ㅡ, in which case the ㅡ changes to ㅏ, as in

• 모르다 --> 물라요
• 흐르다 --> 흐라요
• 고프다 --> 고파요
