Oh boy...
The New Jersey accent
Generally, the so-called Jersey accent or North Jersey accent spoken in northern New Jersey is somewhat closer to General American than the speech of New Yorkers, but still shares enough features with it that two can be considered together as a single dialect group for sociolinguistic purposes. Most colloquial greetings and expressions used in New York are also said by New Jerseyans and with the same frequency. However, aside from the areas immediately closest to New York, north Jersey speech is free of certain New York City features which are heavily stigmatized: the Jersey accent is usually rhotic and æ-tensing is less pronounced than in New York.
This accent is found in the northeast quarter of New Jersey, and is basically the part of the state which is in New York City's metropolitan area but not the dialect region. It includes cities such as Rutherford and Rahway.
Contrary to popular belief, no one in any part of New Jersey ever refers to their state as Joisey. This word is, in fact, a mistaken attempt by non-New Jersey residents to speak with a Jersey accent.
And in Western Monmouth County because everyone here is from Brooklyn, Staten Island, and Long Island.
