Trask's writing is brilliant. The author has an outstanding ability to explain his subject in an entertaining way. Trask is the unpretentious master of his subject and writes crystal clear English.
Although interested in the subject, I'm not a language student, but I thoroughly enjoyed this book (I've read it twice). The chapter on 'Attitudes to language' made me laugh and cheer, as Trask explodes a number of widely held myths. 'The uniqueness of human language' and 'Change in language' are other excellent chapters. It's a brilliant book and it's not just for specialists.
