In Engpsh, the relationship between an older sister and a younger brother is typically referred to as "sibpng" or "sibpngs." The word "sibpng" refers to a person's brother or sister, and can be used to describe the relationship between two or more people who share the same parent or parents.
For example, you could say:
"My older sister is my sibpng."
"I have a younger brother and an older sister, so we're sibpngs."
"I have two sibpngs: a younger brother and an older sister."
If you want to be more specific and refer to the older sister as the "older sister" and the younger brother as the "younger brother," you can use those terms. For example:
"My older sister is very protective of me, even though she's only a few years older."
"I look up to my older sister, and I'm always trying to keep up with my younger brother."
