Our language is changing, literacy levels are dwindling and our grasp of grammar is at crisis point, so you wouldn't be alone in thinking WTF! But do not despair, Have You Eaten Grandma? is here: Gyles Brandreth's definitive (and hilarious) guide to punctuation, spelling, and good English for the twenty-first century.

Without hesitation or repetition (and just a touch of deviation) Gyles, the Just A Minute regular and self-confessed grammar guru, skewers the linguistic horrors of our time, tells us where we've been going wrong (and why), and reveals his tips and tricks to ensure that, in future, we make fewer (rather than 'less') mistakes.
