The Essex dialect is a rapidly disappearing dialect similar to some forms of East Anglian English and is now mainly confined to the north and the east of Essex. It shares vast similarities with both Suffolk and Norfolk dialects, with its own peculiarities. With rapid urbanisation in the twentieth century as well as the impact of the London overspill, Estuary English, a milder form of the London accent predominant largely along the Thames Estuary and thus the name, has become common, mainly in the southern portion of the county. As a result of the growing London influence, the usage of rural accents everywhere and the rural Essex dialect is now normally, but not always, confined to older generations in some of the areas affected and the dialect itself stands in a vulnerable state in those affected parts of the county.

Many of the unique patterns of speech, as well as vocabulary were recorded in the nineteenth and early twentieth centuries The Survey of English Dialects investigated 14 sites in Essex, most of which were in the rural north of the county.

An Essex Dialect Handbook has been published, however recently, the Essex County Records office have recorded a CD of the sounds of Essex dialect speakers in an effort to preserve the dialect.
Frequently sounds are elided to allow the easy flow of speech; e.g.,
Varying use of ‘do’ which is a common trait in Norfolk and Suffolk are exhibited in the Essex dialect.
