has that been lost in Italian?
No, no, it's pretty common and basic to have two letters in a word to strenghten the sound. This never happen in the "end" of a word, but this is easy to fix.
That's why i was confused. I think that most of latin languages can handle it.
TH Is way more harder, due his half soft and hard and sibilant and whatever sound. It's all and nothing in the same sound, so is quite messy. XD
Or also a particoular Z from Romany that is a mix between a Z and a S. Those are all "half" sounds, for me, and i often mess up the tongue with those. XD
