strong contradiction! 

I came here from the article "Italian language". This is the sentence I was reading:

"Standard Italian [...] is somewhat intermediate between the Italo-Dalmatian languages of the South and the Gallo-Romance Northern Italian languages."

The link "Italo-Dalmatian languages" send me here. In this articol I learn that Italo-Western languages are all Romamces languages except Romanian and Sardinian. But I was reading "Italo-Dalmatian languages of the South[ern Italy]" since I thought Southern Italian are Eastern like extint Dalmatian! In the chart one more version: Dalmatian =East and Italian dialect(???) =West. It's crazy!

This confusing classification seems it would not say the truth: North-Italian =West, strictly relative with French, Occitan and Catalan (this is an evidence) and South-Italian =East, with no strict relatives.

Thanks for all
