Relating to brothers or a brotherly relationship; showing the kind of friendship and support you'd expect between brothers.
From Latin 'fraternus' meaning 'of a brother,' which comes from 'frater' (brother). The root is Proto-Indo-European and appears in many languages' words for 'brother.'
The word 'fraternal' gave birth to 'fraternity,' which is why college fraternities call themselves 'brothers'—the whole concept is about recreating that family bond deliberately! Interestingly, identical twins are called 'monozygotic' but fraternal twins are called that because they're like regular siblings born at the same time.
Fraternal (from Latin frater, brother) encodes male kinship as the default model for solidarity, loyalty, and institutional belonging. 'Fraternity' historically excluded women from professional, academic, and civic organizations, cementing brotherhood as the privileged bond.
Use 'collegial,' 'communal,' or 'mutual' to describe bonds of trust and shared purpose without gendered kinship assumptions.

Women built parallel institutional networks (sororities, guilds, mutual aid societies) when excluded from 'fraternal' spaces, demonstrating that solidarity transcends male kinship models.
