Questions & Answers about chingudeuri gongwoneseo norayo.
What’s the role of -들 in 친구들이?
-들 is the plural marker in Korean. It turns 친구 (friend) into 친구들 (friends). It’s optional—Korean often leaves nouns unmarked for number—but adding -들 makes it clear you mean more than one friend.
Why do we attach 이 after 친구들? Couldn’t we use 가 instead?
이/가 are both subject markers, but you choose based on the final sound of the noun:
• Nouns ending in a consonant take 이 (친구들 → 친구들이).
• Nouns ending in a vowel take 가 (학교 → 학교가).
They both mark the noun as the subject of the verb.
What’s the difference between the markers 은/는 and 이/가?
• 은/는 is the topic marker: it introduces or contrasts the topic of conversation.
• 이/가 is the subject marker: it indicates who or what is performing the action or existing in a state.
In 친구들이 공원에서 놀아요, using 이/가 highlights who is playing (i.e. the friends) rather than making friends the general topic.
What does 공원에서 mean, and how does -에서 function here?
-에서 is the location particle used with action verbs.
• 공원 means “park.”• literally means “(they) play at/in the park.” tells you the action takes place.
