We have been doing teaching work in Teacher Training College for the past few years. While teaching, it often occurred to me to write a book, but nothing came of it and the writing work got delayed. But with the new criteria, new policy, semester system at the degree and post-graduate level, this motivation got stronger. Syllabus changes, new components, new topics and content changes were included in the syllabus. Due to this change, while looking at the components of language in the curriculum, students had to find each component from many books. And then I realized that I had to study. Then let us get all the elements in one book and make it convenient for students to study. Such thoughts came to mind and the writing of the book began. Reference books of many expert writers in Marathi, English, Hindi language, books of open university, internet have been reviewed and BEd and M.Ed in all universities. Started writing a book that would be useful to trainees as well as scholars. -Authors
