This article will explain the meaning of dongsaeng, its cultural significance, and how it is used in daily life.
Definition of Dongsaeng
In Korean, “dongsaeng” (동생) refers to a younger sibling or a younger person in a close relationship. The term is gender-neutral in Korean, but there are gender-specific variations when specifying the type of sibling:

| Dongsaeng (동생) | Junior or younger colleague/student | A junior receives guidance and mentorship from a sunbae |
