The Humberhead Levels is a national character area covering a large expanse of flat, low-lying land towards the western end of the Humber estuary in northern England.  The levels occupy the former Glacial Lake Humber, an area bounded to the east by the Yorkshire Wolds and the northern Lincolnshire Edge, a limestone escarpment, and to the west by the southern part of the Yorkshire magnesian limestone ridge.  In the north the levels merge into the slightly more undulating Vale of York close to the Escrick glacial moraine, and to the south merge into the Trent Vale.

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.  Elsewhere in Essex, the dialect and rural accent continues. Humberside was a non-metropolitan and ceremonial county in Northern England from 1 April 1974 until 1 April 1996.  It was composed of land from either side of the Humber Estuary, created from portions of East Riding of Yorkshire, West Riding of Yorkshire, and the district of Lindsey, Lincolnshire.  The county council's headquarters was County Hall at Beverley, inherited from the East Riding, and its largest settlement and only city was Kingston upon Hull.  The county stretched from Wold Newton in its northern tip to a different Wold Newton at its most southern point.  The county still has a limited existence in the form of the Hull and Humber Ports city region. The Cumbrian dialect is a local Northern English dialect in decline, spoken in Cumbria (including historic Cumberland and Westmorland) and surrounding northern England, not to be confused with the area's extinct Celtic language, Cumbric.  Most of the parts of Cumbria have a more North-East English sound to them.  Whilst clearly being a Northern English accent, it shares much vocabulary with Scots.  A "Cumbrian Dictionary of Dialect, Tradition and Folklore" by William Rollinson exists, as well a more contemporary and lighthearted "Cumbrian Dictionary and Phrase Book".
