In ep 139, Stacey interviews Matthew Griffin, an applied linguist and instructor of Spanish who recently published a paper analyzing textbooks for how they present "voseo" to novice learners. "Vos" is a pronoun used widely in Latin America, and not used in European varieties of Spanish. Matthew goes on to talk about the concept of linguistic variation, as well as how and why we should point out and celebrate different varieties of the languages we teach. For those interested in teaching voseo, this interview and the accompanying open-access article provide a practical and research-based exploration of this topic.  For links and show notes, visit https://wp.me/p88mlO-6ia We welcome feedback, resources, and diverse perspectives on this topic!
