Rhetoric: Repetition of prefix

In terms of rhetoric devices, what's it called when the prefixes of consecutive words are the same? Specifically, I am looking at this quote by Winston Churchill made in his speech - Give Us the Tools:

we shall outwit, out-manoeuvre, outfight and outlast ...

The closest word I could think of to describe this is "diacope", however, I am under the impression that it refers exclusively to the repetition of a word or phrase.


Polyptoton :

  • Repetition of words of the same root with different endings.
