Anna Diplosis is a cousin to Ann Timetabole. Ann chooses to reverse her stated ideas (you can see examples in Week 41) whereas Anna likes to take the last word of the statement and for emphasis repeat it as the first word in a juxtaposition.
Anna would quote John Keats, "Beauty is truth, truth beauty."
It goes a bit further with phrases as shown in Anna's favorite folksong by Pete Seeger and Joe Hickerson: " "Where have all the flowers gone... young girls have picked them
Where have all the young girls gone... gone to young men".
Now Iso Colon is a different fellow. He's particular about repetition, both in grammatical structure and in the same number of syllables.
He believes 'many are called, but few are chosen', and he likes to wear a Timex because 'it takes a licking and keeps on ticking'. But he's particularly partial to some advice his grandfather gave him. "How to succeed at business: Have a vision, know your values, and work like crazy."1
Anna and Iso can emphasize ideas or create rhythm in our writing, writing that will more clearly and effectively communicate to our audiences.
