Dr. Andrea O'Reilly is internationally recognized as the founder of Motherhood Studies (2006) and its subfield Maternal Theory (2007), and creator of the concept of Matricentric Feminism, a feminism for and about mothers (2016) and Matricritics, a literary theory and practice for a reading of mother-focused texts (2021). With this collection O'Reilly continues the conversation on the meaning and nature of motherhood initiated by Adrienne Rich in Of Woman Born close to fifty years ago. In In (M)other Words, O'Reilly shares 25 of her chapters and articles published between 2009-2024 to examine the oppressive and empowering dimensions of mothering and to explore motherhood as institution, experience, subjectivity, and empowerment. The collection considers the central themes and theories of motherhood studies including normative motherhood, feminist mothering, maternal regret, matricentric pedagogy, young mothers, academic motherhood, matricentric feminism, matricritics, motherhood and feminism, the motherhood memoir, the twenty-first-century motherhood movement, mothers and daughters, mothers and sons, pandemic mothering, and the motherline.
