Questions & Answers about keompyuteo hwamyeoni keoyo.

What part of speech is 크다 and how does it function in Korean?

크다 is a descriptive verb (형용사). In Korean, adjectives behave like verbs: they conjugate for tense and politeness, take subject markers, and always appear at the end of a clause.

Why does 크다 become 커요 instead of 크어요?

This follows the ㅡ-irregular rule. When a verb or adjective stem ends in ㅡ, you drop that ㅡ before adding a vowel ending. So 크- + -어요 becomes 커요, not 크어요.

What is the function of the particle 이 after 화면? Why not 가?

이/가 marks the subject of the sentence. You attach 이 after a noun ending in a consonant (like 화면), and 가 after a noun ending in a vowel.

Why is there no particle on 컴퓨터? Shouldn’t each noun have its own particle?

Here 컴퓨터 화면 is a single compound noun meaning “computer screen.” In compounds, only the final noun takes the particle. So you treat 컴퓨터 화면 as one unit and attach 이 to 화면.

How can I turn 크다 into an adjective before a noun, as in “big screen”?

Use the pre-noun (adnominal) form 큰.
Example: 큰 화면 means “big screen.”
To use it in a sentence: 큰 화면이 좋아요 (“A big screen is nice.”)

How do I make this sentence negative or turn it into a question?

Negative:

• 화면이 안 커요 (colloquial “The screen isn’t big.”)
• 화면이 크지 않아요 (more formal)

Question:

• 화면이 커요? (with rising intonation)
• 화면이 큽니까? (formal interrogative ending -습니까?)

Can I use the topic marker 은 instead of the subject marker 이 here?

Yes. Changing 이 to 은 marks 화면 as the topic rather than just the subject.

• 화면은 커요.
  This shifts the focus slightly, implying something like “As for the screen, it’s big.”

Could I say 컴퓨터의 화면이 커요? What’s the difference?

Yes. 컴퓨터의 화면 uses the genitive 의 (“of”).

• 컴퓨터의 화면이 커요.
  This is a bit more formal or written. In everyday speech, the compound 컴퓨터 화면 is more common.

Why does the descriptive verb 크다 come at the end of the sentence instead of before the noun, as in English?

Korean follows a subject–object–predicate (S-O-P) word order. Descriptive verbs (형용사) serve as the predicate, so they naturally appear at the end.
