Abstract: The book is Timothy Fitikides’ last available version of Common Mistakes in English. It is aimed at helping EFL and ESL learnersto correct the common mistakes to which they are liable. Regarding the main objective of the book, it is planned that “all the errors dealt with are singled out, for they have to be recognized before they can be corrected; then, correct forms are substituted for incorrect ones; finally, simple explanations are given wherever necessary to justify particular usages” (p. iii). In order to ensure that the principles may become firmly fixed in the learners’ minds, exercises are set at the end.
