The book classifies errors of the EFL Learners learning English as a foreign language and suggests remedial measures to overcome the committing of errors. The book helps the teachers, and syllabus designers concentrate on the grammatical errors, enable the EFL students to improve their English language and make a distinction between errors analysis and contrastive analysis. One of the major features of the book is to reveal the English learner of the problems in supplying the correct grammatical rules of sentences in English language.
