Boston accent

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. A 2006 study co-authored by William Labov claims that the accent remains relatively stable, 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.

Phonological characteristics

Boston accents typically have the cot-caught merger but not the father-bother merger. This means that instead of merging the historical "short o" sound (as in LOT) with the "broad a" (as in PALM) like most other American accents, the Boston accent merges it with the "aw" vowel (as in THOUGHT). Thus, lot, paw, caught, cot, law, wand, rock, talk, doll, wall, etc. all are pronounced with the same open back (often) rounded vowel [ɒ] , while keeping the broad a sound distinct: [a] , as in father, spa, and dark. So, even though the word dark has no /r/ in many Boston accents, it remains pronounced differently from dock because it belongs to Boston's START–PALM class of words versus the LOT–THOUGHT one: dark /dak/ versus dock /dɒk/. Thus, while New York accents have /ɔ/ for paw and /ɑ/ for lot, and Standard British accents have a similar distinction (/ɔː/ versus /ɒ/), Boston accents only have one merged phoneme for both: /ɒ/.

In general, Eastern New England accents have a "short a" vowel /æ/, as in TRAP, that is extremely tensed towards [eə] when it precedes a nasal consonant; thus, man is [meən] and planet is [ˈpʰleənɪʔ].
