모솔 (mosol) — A person who has never dated.

Lesson 93 in our Korean Slang series, adapted from Korean Your Teacher Doesn’t Teach You by Injin Hwang. This expression appears in the book’s shortened expressions section.
What 모솔 means
Short for 모태 솔로, 모솔 can be used by someone talking about their own lack of dating experience. The situation and tone help determine how natural the expression sounds.
A short conversation
A: 연애해 본 적 있어?
B: 아니, 난 모솔이야.
A: Have you dated before?
B: No, I have not.
Use it with care
This is personal information, not an invitation to tease anyone. A person’s worth has nothing to do with relationship history.
A neutral or polite alternative: 연애를 해 본 적이 없어요. — I have never dated.
Try it yourself
Should you use 모솔 to mock another person?
Answer: No. It can be hurtful and invasive. Read the Korean exchange aloud, then replace one detail with something from your own life.
