One form of Gender studies is intersectionality.
Intersectionality as a concept was coined by K. Crenshaw, and has subsequently often been used in research on subjects linked to ethnicity and women. The versatility of the concept is today displayed by its use not only within gender studies but several other fields such as education, law, sociology, theology etc.. While its wide appeal and use might not contribute to precision, its broad applicability is also the major advantage of the concept. We may agree that what intersectionality does, rather than discussing social hierarchies of gender, class, ethnicity, sexuality and age as isolated phenomena, is to allow us to investigate how they mutually construct one another. Intersectionality can therefore be regarded as an analytical tool for understanding multiple discriminations created by the intersection of different categories such as gender, class, ethnicity, sexuality and age.
