Question: What is the dialect that distinguishes British English from World English?

full_context: Document 1: Languages of Northern Ireland: English is the most spoken language in Northern Ireland. There are also two recognised regional languages in Northern Ireland: the Irish language ("see Irish language in Northern Ireland") and the local variety of Scots known as Ulster Scots. Northern Ireland Sign Language and Irish Sign Language have been recognised since 29 March 2004.
Document 2: English in the Commonwealth of Nations: The use of the English language in most member countries of the Commonwealth of Nations was inherited from British colonisation. English is spoken as a first or second language in most of the Commonwealth. In a few countries, such as Cyprus and Malaysia, it does not have official status, but is widely used as a lingua franca. Mozambique is an exception – although English is widely spoken there, it is a former Portuguese colony which joined the Commonwealth in 1996.
Document 3: English of Northumbria: The Northumbrian language or Northumbria English is an English language or dialect of English (""Northumbrian Language"" may only refer to the broadly spoken Northumbrian whereas Northumbrian English may just refer to the Standard English as spoken in Northumbria and featuring various Northumbrian words and forms), and a variant of Northern English with the Geordie dialect being one of the subsets of Northumbrian the others being Northern (north of the River Coquet), Western (from Allendale through Hexham up to Kielder), Southern or Pitmatic (the mining towns such as Ashington and much of Durham) Mackem (Wearside), Smoggie (Teesside) and possibly also Tyke (Yorkshire). It is spoken mainly if not exclusively in the modern day counties of Northumberland and Durham. Whilst all sharing similarities to the more famous Geordie dialect and most of the time not distinguishable by non-native speakers, there are a few differences between said dialects not only between them and Geordie but also each other.
Document 4: The Cambridge Guide to English Usage: The Cambridge Guide to English Usage by Pam Peters is a usage dictionary, giving an up-to-date account of the debatable issues of English usage and written style. It is based on extensive, up-to-date corpus data rather than on the author’s personal intuition or prejudice, and differentiates among US, UK, Canadian and Australian usages. British lexicographer Sidney Landau remarked:
Document 5: Yorkshire dialect: The Yorkshire dialect (also Broad Yorkshire or Tyke) is a Northern English language variety spoken in England's historic county of Yorkshire. The dialect has roots in older languages such as Old English and Old Norse. The Yorkshire Dialect Society exists to promote use of the dialect in both humour and in serious linguistics; there is also an East Riding Dialect Society.
Document 6: Southeast Asian English: Southeast Asian English is the English spoken in Southeast Asia, namely Singapore English (similar to British English), Malaysian English (similar to British English), Brunei English, Philippine English (similar to American English), Thai English, and possibly Hong Kong English.
Document 7: British literature: British literature is literature in the English language from the United Kingdom, Isle of Man, and Channel Islands. Anglo-Saxon (Old English) literature is included, and there is some discussion of Latin and Anglo-Norman literature, where literature in these languages relate to the early development of the English language and literature. There is also some brief discussion of major figures who wrote in Scots, but the main discussion is in the various Scottish literature articles.
Document 8: Rheged: Rheged (] ) was one of the kingdoms of the "Hen Ogledd" ("Old North"), the Brittonic-speaking region of what is now Northern England and southern Scotland, during the post-Roman era and Early Middle Ages. It is recorded in several poetic and bardic sources, although its borders are not described in any of them. Some modern scholars have suggested that it included what is now Cumbria in North West England and possibly extended into Lancashire and Scotland. In some sources, Rheged is intimately associated with the king Urien Rheged and his family. Its inhabitants spoke Cumbric, a Brittonic dialect closely related to Old Welsh.
Document 9: Northumbrian dialect: Northumbrian was a dialect of Old English spoken in the Anglian Kingdom of Northumbria. Together with Mercian, Kentish and West Saxon, it forms one of the sub-categories of Old English devised and employed by modern scholars.
Document 10: English language in England: The English language spoken and written in England encompasses a diverse range of accents and dialects. The dialect forms part of the broader British English, along with other varieties in the United Kingdom. Terms used to refer to the English language spoken and written in England include: English English, Anglo-English and British English in England.
Document 11: Pitmatic: Pitmatic (originally "pitmatical"), also colloquially known as "yakka", is a dialect of English used in the counties of Northumberland and Durham in England. It developed as a separate dialect from Northumbrian and Geordie partly due to the specialised terms used by mineworkers in the local coal pits. For example, in Northumberland and Tyne and Wear the word "Cuddy" is an abbreviation of the name "Cuthbert" but in Durham Pitmatic "cuddy" denotes a horse, specifically a pit pony. In Lowland Scots, "cuddie" usually refers to a donkey or ass but may also denote a short, thick, strong horse.
Document 12: Hen Ogledd: Yr Hen Ogledd (] ), in English the Old North, is the region of Northern England and the southern Scottish Lowlands inhabited by the Celtic Britons of sub-Roman Britain and the Early Middle Ages. Its denizens spoke a variety of the Brittonic language known as Cumbric. The Hen Ogledd was distinct from the parts of northern Britain inhabited by the Picts, Anglo-Saxons, and Scoti as well as from Wales, although the people of the Hen Ogledd were the same Brittonic stock as the Picts, Welsh and Cornish, and the region loomed large in Welsh literature and tradition for centuries after its kingdoms had disappeared.
Document 13: English language in Northern England: The English language in Northern England has been shaped by the region's history of settlement and migration, and today encompasses a group of related dialects known as Northern England English (or, simply, Northern English in the United Kingdom). Historically, the strongest influence on the varieties of the English language spoken in Northern England was the Northumbrian dialect of Old English, but contact with Old Norse during the Viking Age and with Irish English following the Great Famine have produced new and distinctive styles of speech. Some "Northern" traits can be found further south than others: only the northernmost accents of Northumberland and Tyneside retain the pre-Great Vowel Shift pronunciation of words such as "town" ( , ""toon""), but all northern accents lack the – split, and this trait extends a significant distance into the Midlands.
Document 14: Languages of Scotland: The languages of Scotland are the languages spoken or once spoken in Scotland. Each of the numerous languages spoken in Scotland during its recorded linguistic history falls into either the Germanic or Celtic language families. The classification of the Pictish language was once controversial, but it is now generally considered a Celtic language. Today, the main language spoken in Scotland is English, while Scots and Scottish Gaelic are minority languages. The dialect of English spoken in Scotland is referred to as Scottish English.
Document 15: British English: British English is the English language as spoken and written in the United Kingdom. Variations exist in formal, written English in the United Kingdom. For example, the adjective "wee" is almost exclusively used in parts of Scotland and Ireland, and occasionally Yorkshire, whereas "little" is predominant elsewhere. Nevertheless, there is a meaningful degree of uniformity in written English within the United Kingdom, and this could be described by the term British English. The forms of spoken English, however, vary considerably more than in most other areas of the world where English is spoken, so a uniform concept of British English is more difficult to apply to the spoken language. According to Tom McArthur in the "Oxford Guide to World English", British English shares "all the ambiguities and tensions in the word 'British' and as a result can be used and interpreted in two ways, more broadly or more narrowly, within a range of blurring and ambiguity".
