Here's why:
* "Fence" doesn't have a strong rhyme: It's a bit of an odd word for rhymes.
* "Principal parts of a verb" isn't a common phrase: It's more technical language.
Here are some options, with caveats:
* "Tense" is a close rhyme but means "a grammatical category indicating time." It's *related* to verb forms but not the same thing.
* "Concise" is a rhyming word, but it means "brief and to the point," not related to verbs.
To better solve this, we need to clarify what you're looking for. Do you want a word that:
* Rhymes perfectly with "fence"?
* Has a similar meaning to "formed from the principal parts of a verb"?
* Is a more common way to describe this concept?
