Abdullah , which is considered the period of rothacism in Albanian? From
all I could read , it is said this rhotacism should be "recently" but
there is no period of time given.
For the "recentness" of the rothacism I seen an example as "puterë" ( I
am not sure I wrote right down this word) which should be a loan from
italian "putana".
