can anyone give me examples of an extended metaphor or diction?

If one starts with the metaphor of The seeds of discontent have already been sown, an extension could be It remains to see whether weed or flower will spring forth.

The winds were ocean waves, thrashing against the trees’ limbs.The gales remained thereafter, only ceasing when the sun went down. Their waves clashed brilliantly with the water beneath, bringing foam and dying leaves to the shore.'”‘

In this case, the extensions would then be the second two sentences, “The gales remained thereafter, only ceasing…and dying leaves to the shore.”

Also, many fables and fairy tales are often extended metaphors.

Such as short stories like “Where Have You Gone, Charming Billy” by Tim O’Brien

The extended metaphor is a noun.

Extended metaphors break into two types. Implicit and explicit. Implicit means that the poem doesn’t state what one of the objects you are comparing is. Explicit means that the poem clearly state the two comparison items; ex- He is a pig.-R-

Kingston, Ontario’s Tommy L-R created the extended metaphor in 1834.

I didn’t really understand what you meant about diction, but here’s the Wikipedia site for it: http://en.wikipedia.org/wiki/Diction
