I need examples of anaphora and polysyndeton?
In order to be able to identify, or provide examples of a literary device, one must be sure that they know the meaning of the literary device in question.
Polysyndeton is the repetitious use of redundant (able to be omitted without loss of meaning) conjunctions (and, but, for, nor, or, yet, so). What this means is that one of the noted conjunctions is used repeatedly in a sentence, or fragment of a sentence (as in poetry).
An anaphora is the repetition, at the beginning of sentences, using repetitious words. Therefore, a polysyndeton is an anaphora.
As for examples of either, one can look to the Bible. In chapter eight of Genesis, the following show how verses one through nine begin:
And, The, And, And, And, And, And, Also, But
All of the beginnings of the verses (with the exception of verse two) can be omitted without changing the meaning of the line. These are examples of both anaphoras and polysyndetons.
