The author takes a brief look at an often underestimated causal link between gender and the transmission of the Breton language. Experiencing a process of rural exodus and social advancement conditional on language shift to French, women have generally been at the forefront of the abandonment of Breton. Their predominant role in the upbringing of young children also helped to reinforce this trend on a broader scale. However, there are also women who have retained a positive image of Breton: those who had developed a strong relationship with their father, who played the role of initiator into the language.
