Monaco -with Menton- was the extreme western area of the Republic of Genoa (green color) in 1664. Intemelio was spoken in this area, primarily between Ventimiglia and Sanremo.
Since the Renaissance the Ligurian language was spoken in all the territories of the Republic of Genoa; in the western area of the Republic one of its groups (spoken mainly on the coast between Monaco and Sanremo) was called Intemelio and was centered on Ventimiglia.[1]
In the actual Italian area of Ventimiglia there is the most renowned Intemelio: the "Ventimigliese", that stretches from the coast until Piedmont.[citation needed]
The Royasc dialect is connected to the "Ventimigliese", as a mountainous version of the Intemelio that has some Occitan influences.[citation needed]
Intemelio is used by nearly 10,000 people in the area of Ventimiglia of the province of Imperia, but other 40,000 are able to understand it and speak a few sentences of this dialect in western Liguria.[citation needed]
The Ligurian area of Seborga speaks the "Ventimigliese" dialect Intemelio and the so-called Principality of Seborga considered the possibility of using this dialect as the official language.[2]

^Venetian is either grouped with the rest of the Italo-Dalmatian or the Gallo-Italic languages, depending on the linguist, but the major consensus among linguists is that in the dialectal landscape of northern Italy, Veneto dialects are clearly distinguished from Gallo-Italic dialects.
