Boston accent
On the other hand, the Boston accent merges the "short "o"" with the "aw" phoneme: the two classes exemplified by "caught" and "cot" thus both become an often long and rounded , so that "caught", "cot", "law", "wand", "rock", "talk", "doll", and "wall" all are pronounced with the same vowel. By contrast, New York accents and southern New England accents have for "caught" and for "cot" and the London accents have and , respectively. In Boston and some other parts of New England, a few words ending in , e.g., "hot" and "got", can be pronounced with an entirely different phoneme, however, sounding instead like "hut" and "gut", respectively.
Northern England
Northern English accents have not undergone the – split, and a common shibboleth to distinguish them from Southern ones is the Northern use of the short a (the near-open front unrounded vowel) in words such as "bath" and "castle". On the opposite border, most Northern English accents can be distinguished from Scottish accents because they are non-rhotic, although a few rhotic Lancashire accents remain. Other features common to many Northern English accents are the absence of the – split (so "put" and "putt" are homophones), the reduction of the definite article "the" to a glottal stop (usually represented in writing as "t"), and the T-to-R rule that leads to the pronunciation of "t" as a rhotic consonant in phrases like "get up" ().
