(2) lenition of soft stops, (3) its (pre)nasalization, (4) the change of -n- into -r- in the Tosk dialect
of Albanian and a similar process in Old Romanian as well as the Istro‑

and Oltenian dialects of this language, a parallel change of Latin -l- into -r- in common Romanian
and certain Italian dialects.
