Q is never alone in written English, and almost nobody stops to ask why. Why Q Needs U makes a whole book of that unexamined habit, a puzzle anyone who has ever written a sentence has walked past without noticing, and our catalogue files the answer across two shelves at once: education and learning, and politics and society.
That pairing is the interesting part. It suggests a writer for whom language is never merely technical, and for whom the way a thing came to be spelled carries a history of contact and accident along with it. Danny Bate takes the long route through that history rather than the quick one.
The clearest signal of all sits in the credits. Author and narrator are the same name here, and a book about how English looks and sounds gains a great deal from being delivered by the person who wrote it.
