A clan is a group of people connected by real or believed shared ancestry, or by a strong sense of belonging as if they were extended family.

Simple definition

In everyday use, “clan” usually means:

  • An extended family group, often including many generations and branches.
  • People who feel closely united, either by blood, marriage, or long‑term association.
  • A tight-knit group that shares identity, traditions, or common interests.

An example: all your cousins, aunts, uncles, and grandparents gathering every year could be called “your clan.”

Traditional and historical meaning

In anthropology and history, a clan is more specific:

  • A social group whose members claim descent from a common ancestor, sometimes legendary rather than fully documented.
  • Membership is often traced through one line only (father’s side = patriclan, mother’s side = matriclan).
  • Many such clans have rules against marrying within the same clan, treating it as a form of incest.

Clans have existed in many regions, from Scottish Highlands to parts of Africa and Asia, as basic building blocks of social and political organization.

Modern and casual uses (including online)

Today, “clan” is also used more loosely:

  • A big friend group or social circle that sticks together (“our gaming clan,” “the cosplay clan”).
  • Communities in online games or forums that organize as “clans” for teamwork, identity, and reputation.
  • Any group strongly united by common interests or lifestyle, like “the country club clan” or a tight local scene.

In many online spaces and games, “clan” is basically a team or guild with a shared name, rules, and social vibe.

Term What it usually means
Family Immediate or extended relatives (parents, children, siblings, grandparents, etc.).
Clan Larger kin or kin‑like group linked by a common (real or symbolic) ancestor, identity, or shared bond.
Tribe Broader social or political unit that may include multiple clans under one name or leadership.
A clan can be part of a tribe, and a family can be part of a clan; the difference is mainly scale and how formal the group is.

TL;DR: A clan is a tightly connected group of people, often extended family or people who act like family, usually tied together by shared ancestry, identity, or strong common interests.
