This dissertation gathers a series of studies on speech acts that appear in contexts of disagreement, and non-cooperative conversations. With these essays, I open some avenues to study dissent and disagreement within and beyond the field of speech acts theory. By showing both how speech acts behave in conflictual settings, and impact our pragmatic understanding of linguistic items, I integrate agonistic practices of discourse in our understanding of conversation.
