sib (noun):
1. A brother or sister; a sibling. It refers to a person who shares one or both parents with another individual. This term emphasizes the familial relationship between individuals born into the same family. Siblings play a vital role in shaping personal identity and are often significant figures throughout one's life.
2. A member of the same clan, tribe, or kinship group. This definition expands the concept of sib to include individuals who are connected by blood relations beyond immediate siblings. It denotes a broader sense of familial ties, extending to relatives within a larger kinship network.
3. In anthropology, a representation of a kinship group that is based on shared ancestry or lineage. The term is often used to describe a social construct found in various cultures around the world, representing a group of individuals who consider themselves related through descent from a common ancestor. In such societies, sibs can have distinct roles and responsibilities, such as inheritance rights and obligations, and often serve as a foundational unit of social organization.
Overall, sib refers to both the concept and the specific individuals who exist within a kinship group, whether they are siblings, close relatives, or members of a larger ancestral lineage.

The word "sib" has Old English origins. It comes from the Old English word "sibb", which means related by blood, kinsman, or relative. This term is derived from the Proto-Germanic word "*sibjō", meaning "blood relation" or "kinship", which is further related to the Proto-Indo-European root "*seb-" or "*sueb-" meaning "one's own" or "self". Over time, the word "sib" evolved and took on various meanings, including sibling, family relationship, and in some dialects, a friend or comrade.
