'But you can't start a sentence with a conjunction,' primary pupil writes to children's author

Joanna Nadin is a children’s author who has published more than 50 books. She writes speeches. She goes into schools and talks to children about writing.

But she has also committed, in the eyes of the national curriculum, an unforgivable sin: she has started a sentence with a conjunction.

In case she was unaware of her crime against all that is grammatically correct in the world, one of her primary-aged readers has written a letter to advise her of it.

“Dear Joanna,” the letter states. “In your book The Stepmonster you start a sentence with the word and. We have been taught not to start with a conjunction. Why have you done this on page 5?”
