Something or someone is gendered when exhibiting gender-differentiated patterns (e.g. pink and blue as gendered colours, gendered institutions, gendered appearances, etc.). The usage of gender as a verb ( ‘gendering’, ‘engendered’, etc.) is a reflection of a changed understanding of gender as an active ongoing process – something is gendered when it is actively engaged in social processes that produce and reproduce distinctions in gender identities.
