A Boston accent is a local accent of Eastern New England English, native specifically to the city of Boston and its suburbs. Northeastern New England English is classified as traditionally including New Hampshire, Maine, and all of eastern Massachusetts, while some uniquely local vocabulary appears only around Boston.[1][2] A 2006 study co-authored by William Labov claims that the accent remains relatively stable,[3] though a 2018 study suggests the accent's traditional features may be retreating, particularly among the city's younger residents, and becoming increasingly confined to the historically Irish-American neighborhood of South Boston.[4]
