In this article, the author explores rhetorical contextual languaging (as it relates to writing) as critical translingual assemblages of material ecologies[left right arrow]affectual solidarities. Situated in the scholarship on critical translingual literacies, affect, and assemblage theory, two data-theory intervals are featured as exemplars. Data are drawn from global sociopolitical movements and from one Midwest U.S. classroom of adolescent youth enacting multilingual, multimodal, and material literacies. For each interval presented, the author thinks with theory-data to animate the critical translingual assemblages that are produced among writers of diverse racial and linguistic backgrounds, their shared affects and solidarities, and the material landscapes in which they are immersed. She concludes by discussing critical translingual assemblages as an ontological shift in multilingual writing research and as liberatory pedagogies that resist separating writers from the rhetorical contextual languaging and sensations demanded of translingual writing/processes.
