Questions & Answers about sigani jungyohaeyo.
Why is 시간 marked with 이 instead of 가?
In Korean, 이 and 가 are both subject markers. You use 이 after a noun that ends in a consonant, and 가 after a noun that ends in a vowel. Since 시간 ends with the consonant ㄴ, it takes 이: 시간이.
What part of speech is 중요해요?
중요해요 is the polite present-tense form of the descriptive verb (often called an adjective in English) 중요하다 (“to be important”). In Korean, descriptive verbs behave like adjectives do in English but are conjugated like verbs.
Could I say 시간은 중요해요 instead? What’s the difference?
Yes, you can.
- 시간이 중요해요 simply states “Time is important” with no special emphasis beyond presenting it as a fact.
- 시간은 중요해요 uses the topic marker 은, which puts 시간 in the spotlight or sets it as known information. It can imply a contrast (e.g. “Time is important, but…”) or that you’re talking about time specifically rather than something else.
How do I make 시간이 중요해요 more formal?
Switch the polite -해요 ending to the formal -합니다 ending. You get 시간이 중요합니다, which is appropriate in presentations, announcements, or when speaking to someone of much higher status.
