A brother is a male sibling; a cousin is a child of one's aunt or uncle.

Key Differences

A brother is a male who shares both parents with you, or one, in the case of a half-brother. This term defines the closest male sibling relationship within a family. Cousins, however, do not share parents; instead, they share one or more grandparents or another set of ancestors, making their familial connection one step removed from the immediate nuclear family.

Brothers are typically born to the same mother and father, forming a nuclear family unit. They share a direct lineage and usually grow up together, often developing a deep familial bond from childhood. Cousins are related through a shared grandparent or other ancestors, meaning that their parents are siblings. Cousins often share family gatherings and holidays, but may not have the daily familial interactions that brothers do.

The relationship with a brother is usually considered primary in a family hierarchy, with brothers often having a lifelong influence on one another's lives. Cousins, while still important family members, typically have a secondary role in one's life, coming together during larger family assemblies and special occasions.

Inheritance and succession laws in many cultures recognize brothers as direct heirs, reflecting their primary familial position. Cousins are usually considered only when no direct siblings or descendants are present, underlining their more distant familial relationship.

Brothers may have legal obligations to each other, such as the duty to care for a sibling in distress. Cousins generally do not have such legal responsibilities toward one another, reflecting the less immediate nature of their relationship within the extended family.
