Do you think it is acceptable to have a short vocabulary list at the bottom of the page? Mine is a book of short stories illustrating the principles of yoga, for young people. I believe children of 11 and above would understand most of it, but inevitably unusual words are occasionally used. The stories are about the life of a Guru figure, about himself and his family, and are light hearted and amusing and I feel the use of the odd more interesting or challenging word adds to the appeal of the book. What do you think?
