[8] [better source needed] The list of divergent words becomes longer if considering regional Canadian dialects, especially as spoken in the Atlantic provinces and parts of Vancouver Island where significant pockets of British culture still remain.
[further explanation needed] There are a considerable number of different accents within the regions of both the United States and Canada.
In North America, different English dialects of immigrants from England, Scotland, Ireland, and other regions of the British Isles mixed together in the 17th and 18th centuries.
These were developed, built upon, and blended together as new waves of immigration, and migration across the North American continent, developed new dialects in new areas, and as these ways of speaking merged with and assimilated to the greater American dialect mixture that solidified by the mid-18th century.
[9] Below, several major North American English accents are defined by particular characteristics: A majority of North American English (for example, in contrast to British English) includes phonological features that concern consonants, such as rhoticity (full pronunciation of all /r/ sounds), conditioned T-glottalization (with satin pronounced [ˈsæʔn̩], not [ˈsætn̩]), T- and D-flapping (with metal and medal pronounced the same, as [ˈmɛɾɫ̩]), L-velarization (with filling pronounced [ˈfɪɫɪŋ], not [ˈfɪlɪŋ]), as well as features that concern vowel sounds, such as various vowel mergers before /r/ (so that, Mary, marry, and merry are all commonly pronounced the same), raising of pre-voiceless /aɪ/ (with price and bright using a higher vowel sound than prize and bride), the weak vowel merger (with affected and effected often pronounced the same), at least one of the LOT vowel mergers (the LOT–PALM merger is completed among virtually all Americans and the LOT–THOUGHT merger among nearly half, while both are completed among virtually all Canadians), and yod-dropping (with tuesday pronounced /ˈtuzdeɪ/, not /ˈtjuzdeɪ/).
