What are passive verbs? A passive verb is a word that indicates that an action was done in the past. In English, we say something is/are/was done to make it passive. In Korea, there are several ways to make a passive verb. Keep in mind that while passive verbs are used often, it is often more natural just to use the active form of a verb. For example, to find rather than is found, to close rather than is closed, etc. Also, passive verbs also can mean the possibility of taking that action.
AV + (아/어/여)지다
1. When used with an action verb, (아/어/여)지다 turns the verb into a passive verb.
주다 (to give) + (아/어/여)지다 = 주어지다 = to be given = can be given
자르다 (to cut) + ㄹ라 (irregular) + 지다 = 잘라지다 = to be cut = can be but
AV + 이/히/리/기다
2. Generally, when the verb ends in ㅎ, 이다 is the ending.
When the verb ends in ㄱ,ㄷ,ㅂ 히 is the ending.
When the verb ends in ㄹ, 리 is the ending.
When the verb ends in ㄴ,ㅁ,ㅅ,ㅊ 기 is the ending.
놓다 (to put down) + 이 = 놓이다 = to be put down = can be put down
