Corpus research on verbs connected to gendered actants (persons or groups) can reveal patterns of interaction indicative of either the gendered character of human actions or, often, gender stereotypes of writers. Language can also reveal challenging the assigned gender roles and involvement in political or religious dissent. To inquire into what indications language provides of challenging gender stereotypes, we look into Latin-language medieval inquisition records from heresy trials and study differences between male and female agency. In an attempt to empirically test Marxist accounts of medieval heresy as a space for comparative liberation of the suppressed, we focus on medieval women, whose access to some institutions and resources in medieval Christianity was limited, and look at the gendered patterns of agency as signalled by the verbs.
