kvib-antA dhAtutvan na jahati

क्विबन्ता धातुत्वं न जहति

/kvip-enders don't lose roothood.

Or in more words —

rootnouns formed by /kvip are still called /dhAtu even though they are nounbases.

So, when you form a /samAsa like /vizvapA-, that has pA पा + /kvip at the end, the pA- पाॱ is both a nounbase and a root.

This /paribhASA is an exception to the general principle "a /kRt turns a root into a nounbase that is no longer a root".

This rootness is a second-rate citizenship — it will trigger some rules, such as AtodhAtoH, but this pA पा + /kvip is not a root for all intents and purposes. So, don't add a tense after vizvapA- विश्वपाॱ, okay?
