Solidarity
noun /ˌsɒlɪˈdærɪti/ — Unity built on shared interests, goals, or identity.
Definition
Unity or agreement of feeling or action, especially among individuals with a common interest; mutual support within a group.
Beyond the definition
Solidarity is the thing that makes a group more than a collection of individuals. It is what a union feels like when it holds, what a community feels like at its best, what a friendship feels like when tested. The word has political connotations but its deeper meaning is simply: the awareness that your fate is linked with others, and that you choose to act accordingly.
Origin & history
From French solidarite, from solidaire (jointly liable), from Latin solidum (the whole). The financial and legal metaphor: mutual obligation as the foundation of community.
