First of all, I would like to express my heart-felt gratitude to my students who are the source of my inspiration for this book. Their motivations to learn Hindi, and their need for comprehensive online learning materials, have encouraged me to start this journey.
Words fall short to express my deepest appreciation for Regina Gong, and her team members who work for Open Educational Resources (OER) at Michigan State University Libraries. Without Regina and her team this project would not be possible; they have helped me at every stage in this book.
I acknowledge the support that I received from the Department of Linguistics and Germanic, Slavic, Asian and African Studies at MSU. I am forever grateful to all my language teachers at MSU and elsewhere who directly and indirectly have shaped and enriched my teaching skill.
Last, but not least, I want to express my thanks to my family, who never stopped believing in me and have always been very supportive.
