The Irpinian dialect, or Irpino, is the dialect spoken in almost all of the comuni in the Province of Avellino in the Italian region of Campania. It is a variant of the Neapolitan language, but does differ from pure Neapolitan in certain phrases, pronunciation and the use of definite articles. The dialect is heavily influenced by its geographical neighbours. For example, in the northern area of Avellino, there are some undertones of the accent from Benevento. The dialect spoken in Ariano Irpino or the other towns close to the border with Apulia also has a distinct Pugliese tone.
