The nounbase **pur- पुर् f "city" is a rarity.
It is often found in grammar examples, because it is one of the few nounbases ending in r र्. See **pUr पूर्.
Yet, in the sense of "city", the neuter **pura- पुरॱ is far more commonly used.
But, isn't **pur- पुर् found in the modern modern city names Kanpur, Jodhpur, Jabalpur, Udaipur ...?
No; those evolved from puram पुरम्.
