I'm having trouble finding much information on this subject; is it correct to say Greek dialects were generally mutually intelligible, whereas Italian languages were separated into to two branches - Latino-Faliscan and Osco-Umbrian (with dialects within each being mutually intelligible, while cross-branch dialects were mutually UNintelligible)?
What variation could be seen amongst Greek dialects? What commonality could be seen amongst Latin and Oscan languages (ie, how easy would it be for the speaker of one to learn the other)? And would the speakers have noticed the similarities/common origins in their languages? What was it that caused the languages to separate from their common, root language?
Answers to *any* of these questions, are much appreciated
I didn't find the right solution from the internet.
