Studies on teachers' beliefs about vocabulary learning and teaching have focused, so far, on English as a second language (L2), or foreign language (FL), in different contexts but little attention has been given to other L2s and FLs. In this study, 15 Spanish L2 instructors at large universities were interviewed in order to better understand where they stand when it comes to (1) the importance they give to vocabulary, as compared to grammar, in their classes, (2) how they decide which words to teach, and (3) how they assess students' word knowledge. These interviews were subsequently analysed following Grounded Theory. Most instructors declared favoring grammar over vocabulary in their courses because the former is seen as more challenging and useful than the latter and because institutional practices and materials also present such a preference. When it comes to vocabulary selection, most of them declared feeling insecure in their decisions due to lack of access to useful resources and to vocabulary goals not being stated clearly anywhere in the syllabi. This lack of clarity when it comes to vocabulary learning goals also results in doubts about the usefulness of even evaluating word learning at all and an overreliance on informal assessments.
