Formal:
* 보고 싶어요 (bogo sipeo) - This is the most common and polite way to say "miss you".
* 그리워요 (geuriweoyo) - This is also formal and means "I miss you" in a more wistful or longing way.
Informal:
* 보고 싶다 (bogo sipda) - This is the casual version of "bogo sipeo".
* 그리워 (geuriwo) - The informal version of "geuriweoyo".
Adding a name:
You can also add the person's name after "보고 싶어요" or "보고 싶다" for a more personal touch. For example:
* [Name] 보고 싶어요 ( [Name] bogo sipeo) - "[Name], I miss you."
* [Name] 보고 싶다 ( [Name] bogo sipda) - "[Name], I miss you."
Note:
The level of formality depends on the relationship with the person you're speaking to. "보고 싶어요" and "그리워요" are appropriate for someone you respect or are not close to, while "보고 싶다" and "그리워" are more suitable for friends and family.
