This review presents a broad picture of recent work on L2 Spanish in educational contexts. The thematic and geographic scope of the review is wide, in order to capture the diversity of learners and learning contexts of L2 Spanish, just two decades after teaching and learning the language gained impetus worldwide. Traditional second or foreign language learners, heritage learners, immigrants and indigenous children provide a variety of contexts for research that builds on and expands the fields of second and foreign language learning and teaching, applied linguistics and sociolinguistics. Continuing the trend from previous years in SLA, and in connection with research on learners of other languages, main themes in this time period have been the acquisition and teaching of the language system, learning processes, and social contexts of learning. The review is organized thematically according to these main categories.
