This chapter discusses Attic women’s friendships. It takes two contexts of female friendship – the neighbourhood, and female-dominated religious spaces and occasions – and shows how they offered women opportunities to encounter other women, spend time in their company, and construct and define their own spatial and social worlds. It demonstrates the importance of women’s friendships as a source of support, particularly when male relatives failed. It examines two cases in which women were commemorated by friends rather than kin, one of which provided an opportunity for the commemorating woman to discuss her relationship with and feelings about her friend. It concludes with a new examination of the language of female friendship, demonstrating its similarities to the verbal language of male friendship and the behavioural language of kinship. The chapter shows that women’s personal, affective relationships with non-relatives complemented and sometimes supplanted their kin relationships, and constituted a valuable support system.
