Vastese (Vastese: Lu Uâʃtaréule or Lu indialett di lu Uašt, meaning "the dialect of Vasto") is a Romance language spoken in the town of Vasto. It is considered its own language based upon the mutual unintelligibility of it and Italian. It is not spoken by any other town, even the nearby town of Cupello, which is only 9 kilometres (5.6 mi) away.
Today Vastese is spoken monolingually only by residents of Vasto in their 80s and 90s, bilingually by many residents in their 70s, and many middle-aged residents are passive speakers, while most younger residents have no comprehension.
Vastese has more vowel distinctions than Tuscan, Italy's official and standard language. It has vowels that are not in Italian, such as the open front unrounded vowel /æ/. Vastese uses an open back rounded vowel /ɒ/ for the start of the word uâʃtə. It also uses the mid central vowel /ə/. Vastese also uses several diphthongs not used in italian such as /aʊ/, /eʊ/, and /aɪ/.
The influence of /i/, /u/, /Ī/, or /Ū/ upon /æ/, turns it into either /e/ or /je/.
