This is the chairman of Hoksung Electronics.

What happens when it comes to modifiers?

When used as a modifier, -시 is changed to -신 or -시는.

멋지신이 누구세요?
Who is this cool person?
찾으시는 거 있으세요?

The basic rule is that a noun comes after a modifier.

And 것 (거) is a dependent noun, used in combination with a modifier.

There is also a vocabulary of respectful words from the beginning.

Respectful vocabulary is not only expressed using -시.

이거 한번 드셔 보세요.
Please taste it.
집에 아무도 안 계세요?
Is there no one at home?

드시다 and 계시다 are respectful vocabulary.

Let’s learn these along with 시.
