The purpose of this book

English is full of problems for a foreign learner. While some of these problem points are easy to explain, others cause difficulty even for the advanced students and learners. For example, how exactly is the present perfect tense used? What are the differences between big, large and great, between come and go? Is unless the same as if not?

This eBook is a guide to questions of this kind. It addresses close to 240 points which regularly cause problems for the foreign learner. Rules and guidelines are given, using as little linguistic terminology as possible.

How to use this book

Entries are arranged alphabetically. Each entry contains an explanation of a problem, examples of correct usage and typical mistakes. Explanations are, as far as possible, given in simple everyday language.
