Juvenal writes in Satire VI, VIII, line 20:
Nobilitas sola est atque unica virtus.
Translated variously as "Virtue is the one and only nobility", "Nobility is the one only virtue", "Goodness is the only and unparalled nobility".
I want to shorten that to "Virtue is the only Nobility". Would "Nobilitas est unica virtus" be correct? And could I shorten that further to "Nobilitas unica virtus"?
