The paper highlights the role of translation in qualitative research that involves multiple languages. Its particular focus is on untranslatables, that is, those words or phrases in a source language that pose challenges to translators because no direct equivalent is available in the target language. "Untranslatables" create moments of productive difficulty by forcing a critical examination of both the data and the assumptions that framed the research questions. The paper discusses two cases: research with Mandarin-speaking participants on the topic of democracy and democratic subjectivity, and research with Q'eqchi'-speaking participants on the topic of civic engagement and political participation.
