By far the biggest area of typical errors in English is, not surprisingly, here.
If I were to explain in full all the details of how all the grammar structures are used in English (and explain all the terminology in detail), then it would have to be a completely separate book. And website.
Fortunately I do not have to do that as there are already many completely separate books available on the market for that job. I have done my best to include some reasonably detailed explanations for all the faults mentioned, but if you wish to learn more, then it might be necessary for you to consult another book. Sorry.
Meanwhile, have a look at the next few pages. But if you want to know what the problem is with the cartoon above, you'll need to consult Typical Errors in English - the book.
