cousin

This term describes a kinship bond that is often more flexible and less hierarchical than the relationship with a sibling. It frequently carries a connotation of shared childhood memories and extended family loyalty, acting as a bridge between the immediate nuclear family and the wider ancestral network. In social contexts, the word is often used loosely to describe distant relatives or even close family friends in certain cultures, where the biological requirement is relaxed to emphasize a shared social or emotional bond.
