Sisematesse

Sisematesse is a neologism used in online discourse to describe a close, non-romantic bond between women that combines elements of sisterhood and platonic affinity. Proponents use the term to signal a relationship built on mutual trust, ongoing emotional support, and a deep sense of shared life experience, akin to a platonic soulmate.

Origins and etymology are not well attested. The word appears across social media, forums, and some feminist-oriented communities, and is likely a portmanteau derived from "sis" (sister) and "mate" or related terms. Because it lacks formal definition, the precise meaning varies by user and subculture.

Usage and interpretation vary. In some circles, sisematesse emphasizes voluntary selection and agency in choosing close companions, with an emphasis on boundaries and consent. In others, it is framed as an enduring, almost familial bond that persists across time and distance, including coordinated support during challenges.

Reception and relevance. The term has limited traction in academic literature and is largely confined to online communities and contemporary cultural discourse. Critics caution that neologisms can obscure the diverse realities of friendship and risk essentializing gendered experiences.
