New England English
Eastern New England English encompasses Boston and Maine accents, and, according to some sources, the distinct Rhode Island accent. All Eastern New England English is famous for non-rhoticity, meaning it drops the "r" sound everywhere except before a vowel: thus, in words like "car", "card", "fear", and "chowder" (). The phrase "Park the car in Harvard Yard"—dialectally transcribed —is commonly used as a shibboleth, or speech indicator, for the non-rhotic Eastern New England dialect running from Boston north to Maine, and as far west as Worcester, which contrasts with the generally rhotic dialects elsewhere in North America. In all of Eastern New England, except Rhode Island, words like "caught" and "cot" are pronounced identically (both are often rounded, thus: ), because those two vowel sounds have fully merged. A phenomenon called Canadian raising occurs throughout Eastern New England, causing "writer" to have a different stressed vowel sound than "rider", and for the verb "house" to have a different vowel sound than the noun "house". and have relatively back starting positions. The "horse"–"hoarse" distinction is still present to some extent in some areas, as well as the "Mary"–"marry"–"merry" distinction in many speakers.
Rhoticity in English
Though most English varieties in England are non-rhotic today, stemming from a trend toward this in southeastern England accelerating in the very late 1700s onwards, rhotic accents are still found in the West Country (south and west of a line from near Shrewsbury to around Portsmouth), the Corby area, some of Lancashire (north and west of the centre of Manchester), some parts of Yorkshire and Lincolnshire, and in the areas that border Scotland. The prestige form, however, exerts a steady pressure toward non-rhoticity. Thus the urban speech of Bristol or Southampton is more accurately described as variably rhotic, the degree of rhoticity being reduced as one moves up the class and formality scales.
