An avenue with a long official name, for example, Mass-av (instead of Massachusetts Avenue) and Comm-av (rather than Commonwealth Avenue). For many years, the Boston Globe even used "av." (yes, in lower case) rather than "Ave."
In Cambridge, a Havihd student. In Sommaville, a Cambridge resident. Local speakers argue about its derivation: Some say its from "Bahnyahd," a derisive term for Hahvihd Yahd; others argue it comes from the old MBTA cah bahns just outside the Squayuh (the bahns went away when the Red Line was extended to Sommaville).
