However, it's important to note that Korean uses different terms depending on the relative's gender and your relationship with them. Here's a breakdown:
* 조카딸 (jokatdal): This is the general term for niece. It's used for the daughter of your brother or sister.
* 사촌 동생 (sachon dongsaeng): This means "cousin younger sibling," which is used for your niece if she's the daughter of your cousin.
Therefore, to accurately convey "pamangkin na babae" in Korean, you need to specify the relationship between you and the niece's parents.
