Polyptoton
Polyptoton is the use of the same word or word root in different grammatical forms or contexts within close proximity. Unlike epizeuxis (exact repetition) or parallelism (matched syntax with substituted words), polyptoton keeps the root word the same but shifts its grammatical function, tense, or modal context, so that the shift itself carries the meaning.
Polyptoton lets a speaker explore the range of a single concept by holding the word still and moving the grammar around it. The effect is precision through variation: the listener registers both the sameness of the word and the difference in what it is doing, so two related but distinct ideas (inability and refusal, physical motion and emotional motion) are held together in the same sound.

“Just say you've always wondered”
Uncle Jerry identifies the word 'wonder' as carrying multiple grammatical forms and meanings across the song. In 'just say you've always wondered' it is a past-tense verb meaning contemplated or regretted. In 'I wonder' and 'will I always wonder' it is a present and future verb. In Uncle Jerry's reading, 'wonder' also carries the noun sense: 'a wonder, it's a fantasy, it's not real, it's unreal.' The same root word shifts function and meaning each time it appears, and this shifting is what Uncle Jerry calls 'the song's governing poetic principle.'
The polyptoton of 'wonder' binds the song together: the word's grammatical shifts (wondered, wonder, always wonder) track the speaker's movement from imagining someone else's thoughts to interrogating her own, while the noun sense ('a wonder') reminds the listener that none of these imaginings are real.
“Can't stop, won't stop movin'”
Uncle Jerry identifies polyptoton in 'can't stop, won't stop': the same word 'stop' is used in two slightly different grammatical contexts. 'Can't stop' highlights inability, while 'won't stop' highlights refusal, a deliberate choice. The first suggests that the momentum of movement has taken over; the second makes it a conscious decision.
The distinction between 'can't' and 'won't' captures both the compulsive nature of Taylor's creative drive and her deliberate choice to keep going despite criticism. She is unable to stop doing what she does, and she refuses to stop.
