" Understanding Morphology'' is a new textbook designed primary for university students of linguistics and translation. I have tried to do much more than simply provide coverage of morphologic phenomena peculiar to our university students of linguistics and translation. As the title suggests, I have attempted an introduction to English morphology, hence the book has been organized to be simple and easy to use. " Understanding Morphology'' is a valuable textbook and reference tool for improve our students' four skills.This invaluable textbook can help our students avoid overusing any particular morphemes, thus making their writing more lively and interesting. An important features of this book is that the contents are graded in order to cater for the different needs and expectations of its readers ,thus most of the materials is suitable for all readers. But certain sections are signposted as '' advanced'' and are intended for those who are ready to pursue morphology in greater depth.
