FAQs (What You Might Still Wonder About)
1. Can I just say “동생” instead of “여동생”?
Yes! In casual conversation, Koreans often omit 여 and simply say 동생, which means “younger sibling” and can refer to either a sister or brother.
2. Are there different words based on the speaker’s gender?
For younger sister, 여동생 is universal and doesn’t depend on the speaker’s gender. However, for older sister, women use 언니 (eonni) and men use 누나 (nuna).
3. How do I say “my younger sister” in a polite sentence?
A formal example: “저의 여동생은 대학교에 다니고 있어요.” (Jeoui yeodongsaeng-eun daehakgyo-e danigo isseoyo.) → “My younger sister is attending college.”
4. How do I refer to younger sisters in extended or in-law relationships?
Variations include: Step‑younger‑sister: 의붓동생 (uibutdongsaeng) Half‑younger‑sister: 이복동생 (ibokdongsaeng) Sister‑in‑law (husband’s brother’s wife or wife’s younger sister): terms differ depending on context, like 동서 or 처제.
5. How do I say “twin younger sister” in Korean?
You can say 쌍둥이 여동생 (ssang-dung-i yeo-dong-saeng). If she is born even a few minutes after you, she is technically your younger sister in Korea! However, twins in Korea often just call each other by name or friend-like terms since they are the same age.
6. What is the cozy or cute way to call my younger sister?
If you want to sound affectionate, you can add “우리” (uri – our/my) in front of the word, making it 우리 동생 (uri dong-saeng) or 우리 막내 (uri mang-nae) if she is the youngest child in the family. It sounds very warm and loving!
7. Is it okay to use “여동생” when texting or messaging her?
No, even in text messages (like KakaoTalk), you should avoid addressing her as “여동생”. Instead, just type her Name + 아/야 (e.g., “수진아 뭐해?”) or use friendly family nicknames. Remember, “여동생” is only for describing her to other people!
