Informal Polite Form of Korean Verbs and Adjectives
To study this grammar point, please make sure you understand the following:
Informal polite speech level is the most common form of speech in daily conversation. It is also called Haeyoche(해요체). It is mainly used between strangers to demonstrate some kind of social distance, or when talking to people more senior to show respect.
When you look up a verb or adjective in a dictionary, it is always written with a 다 ending. In order to conjugate a Korean verb or adjective to its informal polite form, identify its alternate stem and use 어-type conjugation to attach 아요 or 어요 to it.
- If the last vowel of the stem is 아 or 오, attach 아요 to the stem.
- If the last vowel is 으 and its previous vowel is 아 or 오, attach 아요 to the stem.
- Otherwise, attach 어요 to it.
- Do vowel contraction if necessary.
Exception: Use original stems to conjugate ㄹ-irregular verbs and adjectives.*
