[split] EVA-y as Latin "-us" etc.

2.Double consonants (ll, rr etc.), which are common in Italian, are almost non-existent in Latin.
This would have something in common with VM. There also see no double consonants

Whitaker's Words for 39403 Latin roots gives the following stats:
1537 instances of "ll" (3.9%)
635 instances of "rr" (1.6%)

Don't think that this counts as "almost non-existent".
