We all use reference books, as far as I know, and we should. How else do we learn?I'd never heard of "gaff" (for Jolan's 5) yesterday, so two more words filed away in what passes as a brain (gaffe as well).
I'm off to make a children's story book about a ladybird called Alice (I take it you don't eat them, GK, though I saw people eating scorpions and grasshoppers in China).
