Questions & Answers about naneun jeonhyeo pigonhaji anha.

Why is 는 attached to 나 in 나는?

는 is the topic marker. 나는 means “as for me / I (topic).” It sets “me” as the topic of the sentence.

• Using 내가 (subject marker 가) instead would emphasize “I” as the specific doer/holder of the state: 내가 전혀 피곤하지 않아 (“It’s I who isn’t tired”).
• In everyday speech, the topic often gets dropped if it’s obvious: 전혀 피곤하지 않아.
• In polite speech, switch 나 to the humble 저: 저는 전혀 피곤하지 않아요.

Can I drop 나는?

Yes. Korean frequently omits the subject when it’s clear from context. 전혀 피곤하지 않아. is perfectly natural. You can also use the spoken contraction 난 for 나는: 난 전혀 피곤하지 않아.

Why is the negative formed as 피곤하지 않아 instead of just using 안?

Korean has two common negatives:

• Adverb 안 before the predicate: 안 피곤해
• Auxiliary -지 않다 after the stem: 피곤하지 않아
  Both are correct. 안 feels a bit more casual; -지 않다 is slightly more neutral/formal or explicit. With “at all,” both sound fine: 전혀 안 피곤해 = 전혀 피곤하지 않아.

What exactly does 전혀 mean, and does it require a negative?
