Title: Oxford A-Z of Grammar and Punctuation Author: John Seely Level: Intermediate

This book is not for the faint hearted! It does exactly what it says on the cover, nothing more nothing less! For the native speaker and advanced speaker it is an indispensable, light weight reference. However, I would hesitate to recommend this to anyone less than upper intermediate level as the explanations and examples can be quite difficult to understand.

I would highly recommend this to English teachers to cover those moments when you can not quite remember the exact difference between a 'relative clause' and a 'finite verb'
