Take the initial letter of each word in a common phrase, saying or longer quote, rearrange them and form a word or phrase that summarises or relates to it. Such anagrams of acrostics I call ANACROGRAMS. Sounds passe? Maybe. Impossible? Usually: those I'll present later are a tiny fraction of all the candidates considered. But since the latter in turn form a very tiny fraction of possible sources, this new game opens virtually unlimited vistas for meaningful word play, perhaps as much as straight anagramming.
