NW (Washington, Idaho, Oregon territories):
English, but referred to as "Newglish" (combination of the letters NW and English) - pretty much standard English with little derivation.Ê However, I think there should be a greater propensity for using Native American words in regular conversation since much of the area still has a large Native American population and many of the cities/counties have NA names.

SW (California, Nevada, Utah):
Again English, but referred to as"Ebainglish" - twisted combination of Spanish (for obvious reasons), Ebonics and standard English.Ê I'm thinking the big difference here will be in grammar and sentence structure because of Ebonics and many more Spanish/Mexican words are common vocabulary.

North-Mid-West (Montana, Wyoming, the Dakotas, Colorado, Nebraska):
Because of it's central location, this is the one area that still refers to it's language as "English" and has had few changes made to it - pretty much just same-old same-old English. Little to no derivation.

South-Mid-West (Texas, Oklahoma and New Mexico)
"Vacaboglish" (twisted combination of the Spanish word "Vaca" (meaning cow) and "boy" and English (so technically "Cowboy-English/Spanish")). - Combination of Spanish and English, but with heavy/thick "Cowboy" style accents.Ê Because of the accents, many common words are now thought of as "new" words, but with the same meanings, such as "Ah" instead of "I" and "figger" instead of "figure" so common sentences like "I figure the figure of my pint of beer is quite fine" has become something like "Ah figger the figger o' mah cervesa is quat fahn."Ê

South-East (Arkansas, Louisiana, Mississippi, Tennessee, Alabama, Florida, Georgia, South Carolina and North Carolina):
"Creole" - with the breakdown of actual education of English as a language, Creole has taken over the South-Eastern United States.Ê Thick thick accents and a gross combination of English, Native American and French have made this probably the most difficult of the "New" languages for people to learn and/or interpret.Ê There should also be a heavy Baptist influence with biblical references thrown in as common speech/euphamisms.

East-Central (Illinois, Wisconsin, Iowa, Minnesota, Michigan, Missouri, Indiana, Ohio, Kentucky):
"Eeenglich" - Ever talk to someone from Wisconsin or Illinois?Ê Ever pay attention to their accent?Ê Watch "Drop Dead Gorgeous" and you'll see what I mean in a heartbeat.Ê However, there is a more gutteral sound to it now as well because of the large black population in the area, primarily focused in Illinois andMichigan, but after the breakdown of society they just spread like everybody else, and so did their accents/style of speech.

East (Washington DC, Maryland, Pennsylvania, Delaware, the Virginias)
"Ehnglish" - honestly, I dont' know much about this part of the country, so I'll have to guess mostly
