Questions & Answers about haksaengdeuri jilmuneul haeyo.
Why is 들 added to 학생? Is it mandatory?
The suffix 들 is a plural marker. Adding it to 학생 turns “student” into “students.” It’s not strictly mandatory—if context already shows you’re talking about more than one student, you can drop 들. But including it makes the plurality explicit.
Why is the subject marked with 이 in 학생들이? When do I use 이 vs. 가?
In Korean, 이/가 mark the grammatical subject. You attach 이 after a noun ending in a consonant and 가 after a noun ending in a vowel. Since 학생들 ends in the consonant ㄹ, you add 이 to get 학생들이.
Why does 질문 take 을 in 질문을 해요? What’s the function of 을?
을/를 are object markers. They show what the verb directly acts upon. You use 을 after a consonant and 를 after a vowel. Here, 질문 ends with ㄴ, so it takes 을, indicating that “questions” are the direct object of “ask.”
