For a help in building copia, I bookmarked this handy little link today: The Phrase Finder. You can search for any phrase—sometimes hard to do in a dictionary! There is also a Phrase Thesaurus which gives you a list of phrases related to the word you input. And there are links to lovely lists: Proverbs, Phrases Coined by Shakespeare, Nautical Phrases, and Famous Last Words. Well, okay, that last one includes some not-so-lovely and even downright chilling selections, but interesting nonetheless. And those just might make some top-notch *anecdotes for an elaboration!
*Nota Bene: Anecdote Elaboration is a compostion exercise taught in Cottage Press Poetics & Progym I. 😀
