This book brings together eleven peer-reviewed chapters of cutting-edge research produced by both established and rising scholars in the field. Given that this volume is inspired by papers from the 25th iteration of the Hispanic Linguistics Symposium, the editors track the development of the field in the last quarter century and have organized the volume into three sections (linguistic structure and variation, US Spanish and heritage speakers, applied linguistics) reflecting current research trends. This edited volume will be a welcome resource for advanced undergraduate students, incoming and advanced graduate students, and researchers in the field, as well as Spanish language educators at all levels.
