Thanks Chris!

You’re welcome! In that case the monumental work of Battus on ‘Opperlans’ would be a joy for you. It is an encyclopedia of all possible patterns of language, i.e. Allagrams, anagrams, alliterations, lipograms, a-poems, e-poems, etc., 676 of them. Wordplay, you know

Alas, it is untranslatable. You would have to learn Dutch and after that ‘Dutch on holiday’. I will nevertheless show you it truly exists. At left the dictionary, at right the encyclopedia.
