The review by Mastoor Al Kaboody of the second edition of *Vocabulary in Language Teaching* by Schmitt and Schmitt (2020) highlights the book's comprehensive and accessible approach to vocabulary instruction for language teachers. The book covers nine chapters that delve into various aspects of vocabulary acquisition, instruction, and assessment. Key themes include the connection between empirical research, theoretical frameworks, lexical development, classroom practices, and the central role of vocabulary in second language (L2) instruction. Each chapter provides pedagogical applications and discusses the importance of integrating vocabulary into the curriculum. The authors emphasize the advantages of corpus-based evidence and the distinction between incidental and intentional vocabulary learning. The book is written for language teachers and teacher trainees, offering clear and practical guidance based on extensive research. While it is a valuable resource for both educators and researchers, it may lack detailed discussions on trends and further research directions. Overall, the book is a significant contribution to the field, providing a well-informed guide for making decisions in vocabulary instruction and assessment.The review by Mastoor Al Kaboody of the second edition of *Vocabulary in Language Teaching* by Schmitt and Schmitt (2020) highlights the book's comprehensive and accessible approach to vocabulary instruction for language teachers.
