Imperative sentences in Korean grammar are used to give orders, make requests, or give advice. They usually end with the verb stem and either 아/어/여라 or 하다 conjugated directly to the verb stem. The polite form of imperative sentences uses 주세요 after the verb. Korean imperative sentences differ from English because the subject can often be omitted when the context is clear. If the speaker is talking in an informal or casual tone, the verbs usually end in 아/어/여. Here are some exercises to help you practice forming imperative sentences in Korean.
