In the example sentence for egregious Anu (or someone else) wrote Azzuri meaning the Italian football players.
The meaning is obvious because the national shirt is sky-blue= azzurro.
My question is: why so often English writers mispell Italian names in double letters?
Even my name Emanuela is very very often written as Emanuella, and I cannot figure out why.

Just a curiosity:
We call Principe azzurro your Prince Charming - I suppose because he wears a sky-blue cloak
