Root Word Alliteration
The poetic style which repeats a slightly modified root word to emphasize that root word while creating a rhyme.
Examples of "root word alliteration" are, "love—that unexplainably still unexplained phenomenon which in this era of perfection still makes the world go round—appears to take on a life of its own to grow and is irrefutably known to quickly deactivate reason in order to satisfy one or both lover's needs." And "It's better to be safe than sorry," said a tax-collector to a tax-evader who worked as a stocks and bond trader and wrestled against alligators."
