Western American English

Western American English (also known as Western U.S. English or in the U.S., simply, Western) is a variety of American English that largely unites the entire western half of the United States as a single dialect region, including the states of California, Nevada, Arizona, Utah, New Mexico, Colorado, and Wyoming. It also generally encompasses Washington, Oregon, Idaho, and Montana, some of whose speakers are classified additionally under Pacific Northwest English. The West was the last area in the United States to be reached during the gradual westward expansion of English-speaking settlement and its history shows considerable mixing of the linguistic patterns of other regions. As the settlement populations are relatively young when compared with other regions, the American West is a dialect region in formation.

The Western dialect of American English is somewhat variable and not necessarily distinct from "General American." Western American English is characterized primarily by two phonological features: the cot–caught merger (as distinct from most Northern and Southern U.S. English) and the fronting of /uː/ but not /oʊ/ (as distinct from most Southern and Midland U.S. English, in which both of those vowels are fronted, as well as from most Northern U.S. English, in which both of these remain backed).

Like most Canadian dialects and younger General American, /ɑ/ allophones remain back and may be either rounded or unrounded due to a merger between /ɒ/ and /ɔː/ (commonly represented in conservative General American, respectively, so that words like cot and caught, or pod and pawed, are perfect homophones (except in San Francisco). In the West, there is less Canadian raising of the /aʊ/ diphthong than in Canada, and yet fairly common Canadian raising of the /aɪ/ diphthong. A significant minority of Western speakers have the pin–pen merger or a closeness to the merger, especially around Bakersfield, California, though it is a sound typically associated with Southern U.S. dialect, which influenced the area. The West is entirely rhotic and the Mary–marry–merry merger is complete (as in most of North America), so that words like Mary, marry, and merry are all pronounced identically because of the merger of all three of those vowels' sounds when before r (towards [ɛ]).
