What is the role of 수업이 in this sentence?
수업 means “class” or “lesson.” The -이 is the subject marker, indicating that 수업 is the subject of the verb 끝났어요.
What does 끝났어요 mean, and what is its basic dictionary form?
The dictionary (infinitive) form is 끝나다, meaning “to end” or “to finish” (intransitive). 끝났어요 is its polite past-tense form, so it means “has ended” or “finished.”
How do you get from 끝나다 to 끝났어요?
- Remove -다 from 끝나다, leaving the stem 끝나-.
- Add the past tense marker -었- → 끝나 + 었 = 끝났-.
- Attach the polite ending -어요 → 끝났 + 어요 = 끝났어요.
Why isn’t it 끝나요?
끝나요 is the polite present tense (“ends” or “is ending”). Since the speaker wants to say that the class has already ended, they use the past tense 끝났어요 instead of the present 끝나요.
How would I turn 수업이 끝났어요 into a question?
