Recommended for teachers, useful to clarify certain points and for definitions. Also for university students studying English Language. It may be a bit intensive for the average A level student unless they are very committed.
Work-a-day. Useful modern, practical grammar. The endless recreation of myriads of technical terms is reflected in yet more of them in this Grammar. However, if you can tolerate this seemingly pointless exercise this is very usable. It falls into the category of 'common sense tells you that this just isn't a sentence' but 'you have to call it a minor sentence to be politically correct'. Sigh - the dreary head of P.C. infects it here and there. However, if you can also put that aside, it's useful.
