polyptoton

polyptoton, the rhetorical repetition within the same sentence of a word in a different case, inflection, or voice or of etymologically related words in different parts of speech. The device is exemplified in the following lines from T.S. Eliot’s poem “The Dry Salvages” (1941):

There is no end of it, the voiceless wailing,
No end to the withering of withered flowers,
To the movement of pain that is painless and motionless,
To the drift of the sea and the drifting wreckage,
The bone’s prayer to Death its God. Only the hardly, barely prayable
Prayer of the one Annunciation.
