Question 1

In 초를 켤 때 조심하세요., what does the particle 를 after 초 indicate?

Accepted Answer

The particle 를 marks 초 (candle) as the direct object of the verb 켜다 (to light). It shows that you are lighting the candle. Without 를, the sentence would lack an explicit object.

Question 2

Why is the verb in the form 켤 before 때 instead of 켜다 때 or something else?

Accepted Answer

To say “when [something happens]” in Korean, you attach -을/-ㄹ 때 to the verb stem. The dictionary form is 켜다, stem 켜-, plus -ㄹ (because the stem ends in a vowel) gives 켤, so 켤 때 = “when (you) light.”

Question 3

What is the function of -때 in 켤 때?

Accepted Answer

때 means “time” or “when.” When attached to a verb stem with -을/-ㄹ 때, it turns the verb into an adverbial phrase: “when doing X.” Here, 켤 때 = “when you light.”

Question 4

What does 조심하세요 mean, and why is this form used?

Accepted Answer

조심하세요 is the polite imperative form of 조심하다 (to be careful). The ending -세요 adds polite/honorific nuance, so 조심하세요 means “please be careful.”

Question 5

Why is there no explicit subject like “you” in this sentence?

Accepted Answer

Korean often omits subjects when they are clear from context. In an imperative sentence like this, the listener (“you”) is understood. So 초를 켤 때 조심하세요 literally implies “(You) when you light the candle, (you) be careful.”

Question 6

If I want to make this sentence more formal or honorific, how would it change?

Accepted Answer

You could add the honorific -시- and use a more formal ending: 초를 켜실 때 조심하십시오. Here, 켜실 때 is the honorific “when you light,” and 조심하십시오 is the formal imperative “please be careful.”
