Questions & Answers about sueop biyongi bissayo.

Why is 비용 used here instead of 값 or 가격?

All three words relate to cost, but they have subtle differences. 값 is a more direct, everyday word for “price” (often for items). 가격 is a general term for “price” or “rate,” often used in commerce. 비용 literally means “cost” or “expense,” emphasizing the amount you have to spend (often for services, projects, or fees). Since 수업 비용 focuses on the expense of taking a class, 비용 is most natural.

What is the function of the particle 이 after 비용?

The particle 이 is the subject marker in Korean. It attaches to nouns ending in a consonant (if the noun ends in a vowel, you use 가). Here, 수업 비용이 marks “class cost” as the subject of the descriptive verb 비싸요.

Could I use the topic particle 은 and say 수업 비용은 비싸요? What’s the difference?

Yes, you can. 수업 비용은 비싸요 sets 수업 비용 as the topic and often suggests a contrast or comparison (e.g., “As for the class fee, it’s expensive [compared to something else]”). 수업 비용이 비싸요 simply states a new fact about the cost without implying contrast.

Why not just say 수업이 비싸요 to mean “The class is expensive”?
