I think this sentence pretty much invalidates the analysis:
“Each word is counted once, so pimps, pimp, pimping, and pimpin are four unique words.”
That occurred to me too. But, in Moby Dick, whale, whaled, whaler and whaling would also be four unique words.
Under that criteria, from “Love’s Labour’s Lost”, light should count as four words. Much more distinct than variations of the word “pimp”.
‘Light, seeking light, doth light of light beguile.’
Bet he didn’t.
Although I could see a rapper rip that off and butcher it.
‘Pimp looking fo pimp, done gone pimpin and got all pimped up, pimperfect.’
