River Wear
The River Wear (, ) in Northern England rises in the Pennines and flows eastwards, mostly through County Durham, to the North Sea in the City of Sunderland. At long, it is one of the region's longest rivers. The Wear wends in a steep valley through the cathedral city of Durham and gives its name to Weardale in its upper reach and Wearside by its mouth. Etymology The origin behind the hydronym ''Wear'' is uncertain but is generally understood to be Celtic. The ''River Vedra'' on the Roman Map of Britain may very well be the River Wear. The name may be derived from Brittonic ''*wejr'' (<''*wẹ:drā''), which meant "a bend" (cf. Welsh ''-gwair-''). An alternative but very problematic etymology might involve ''*wẹ:d-r-'', from a lengthened form of the |
Weir
A weir or low-head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the water level. Weirs are also used to control the flow of water for outlets of lakes, ponds, and reservoirs. There are many weir designs, but commonly water flows freely over the top of the weir crest before cascading down to a lower level. There is no single definition as to what constitutes a weir. ''Weir'' can also refer to the skimmer found in most in-ground swimming pools, which controls the flow of water pulled into the filtering system. Etymology The word likely originated from Middle English ''were'', Old English ''wer'', a derivative of the root of the verb ''werian,'' meaning "to defend, dam". The German cognate is ''Wehr'', which means the same as English weir. Function Commonly, weirs are used to prevent flooding, measure water discharge, and help render rivers more Navigability, navigable by boat. In ...

City Of Sunderland
Sunderland () is a port city and metropolitan borough in Tyne and Wear, England. It is a port at the mouth of the River Wear on the North Sea, approximately south-east of Newcastle upon Tyne. It is the most populous settlement in the Wearside conurbation and the second most populous settlement in North East England after Newcastle. Sunderland was once known as 'the largest shipbuilding town in the world' and once made a quarter of all of the world's ships from its famous yards, which date back to 1346 on the River Wear. The centre of the modern city is an amalgamation of three settlements founded in the Anglo-Saxon era: Monkwearmouth, on the north bank of the Wear, and Sunderland and Bishopwearmouth on the south bank. Monkwearmouth contains St Peter's Church, which was founded in 674 and formed part of Monkwearmouth–Jarrow Abbey, a significant centre of learning in the seventh and eighth centuries. Sunderland was a fishing settlement and later a port, being granted a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devonian
The Devonian ( ) is a period (geology), geologic period and system (stratigraphy), system of the Paleozoic era (geology), era during the Phanerozoic eon (geology), eon, spanning 60.3 million years from the end of the preceding Silurian period at million years ago (Megaannum, Ma), to the beginning of the succeeding Carboniferous period at Ma. It is the fourth period of both the Paleozoic and the Phanerozoic. It is named after Devon, South West England, where rocks from this period were first studied. The first significant evolutionary radiation of history of life#Colonization of land, life on land occurred during the Devonian, as free-spore, sporing land plants (pteridophytes) began to spread across dry land, forming extensive coal forests which covered the continents. By the middle of the Devonian, several groups of vascular plants had evolved leaf, leaves and true roots, and by the end of the period the first seed-bearing plants (Pteridospermatophyta, pteridospermatophyt ...

Caledonian Orogeny
The Caledonian orogeny was a mountain-building cycle recorded in the northern parts of the British Isles, the Scandinavian Caledonides, Svalbard, eastern Greenland and parts of north-central Europe. The Caledonian orogeny encompasses events that occurred from the Ordovician to Early Devonian, roughly 490–390 million years ago ( Ma). It was caused by the closure of the Iapetus Ocean when the Laurentia and Baltica continents and the Avalonia microcontinent collided. The orogeny is named for Caledonia, the Latin name for Scotland. The term was first used in 1885 by Austrian geologist Eduard Suess for an episode of mountain building in northern Europe that predated the Devonian period. Geologists like Émile Haug and Hans Stille saw the Caledonian event as one of several episodic phases of mountain building that had occurred during Earth's history.McKerrow ''et al.'' (2002) Current understanding has it that the Caledonian orogeny encompasses a number of tectonic phases th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alston Block
The Alston Block is a term used by geologists to describe the geological structure of the North Pennines of northern England and which forms a part of the Pennine Block & Basin Province which originated during the Carboniferous period. It is defined by the Stublick and Ninety Fathom faults to the north, the Pennine Fault to the west and the Stainmore Trough to the south. It is in essence a horst underlain by the Weardale Granite which provides sufficient buoyancy to maintain this piece of the upper crust as an area of raised relief. To its west lies the Vale of Eden and to its north is the half-graben A half-graben is a geological structure bounded by a fault along one side of its boundaries, unlike a full graben where a depressed block of land is bordered by parallel faults. Rift and fault structure A rift is a region where the lithosphere ... of the Northumberland Trough.British Geological Survey. 1996, ''Tectonic Map of Britain, Ireland & adjacent areas'', Pharaoh ...

Quair Water
The Quair Water is a tributary of the River Tweed in the Scottish Borders area of Scotland. Its name is related to Traquair. Etymology The name ''Quair'' has a Brittonic etymology. It may be derived from the element ''*wejr'' (<''*wẹ:drā'') meaning "a bend, something curved or twisted" (cf. ''gweir'', Welsh ''gwair, gwŷr''; in compounds). The name could also descend from ''*wẹ:Σ-'' or ''*wiΣ'', both forms of the root ''*wei'' which has a basic sense of "flowing", with the suffix '' –urā-''.

River Wyre
The River Wyre, in Lancashire, England, flows into the Irish Sea at Fleetwood. It is 28 miles (45 km) long and has a sheltered estuary which penetrates deep into the Fylde peninsula. Etymology The name ''Wyre'' is of pre-Roman, likely, if specific, Common Brittonic origin. It may be derived from ''*wiΣ-'', a form of the element ', with a basic sense of "flowing", with the suffix '. The River Wyre possibly shares its etymology with other Hydronym, river names, including the River Wear, Wear in County Durham and the Quair Water in Scotland. The river's name possibly means 'winding river' in Celtic. Geography The river rises in the Forest of Bowland in central Lancashire, as two distinct tributaries—the Tarnbrook Wyre and the Marshaw Wyre—whose confluence is near the village of Abbeystead. In 1984, a pumping station, built just below the confluence as part of a water transfer scheme in the 1980s, saw the Abbeystead disaster, an explosion in which 16 people were kill ...

Proto-Indo-European Language
Proto-Indo-European (PIE) is the reconstructed common ancestor of the Indo-European language family. No direct record of Proto-Indo-European exists; its proposed features have been derived by linguistic reconstruction from documented Indo-European languages. Far more work has gone into reconstructing PIE than any other proto-language, and it is the best understood of all proto-languages of its age. The majority of linguistic work during the 19th century was devoted to the reconstruction of PIE and its daughter languages, and many of the modern techniques of linguistic reconstruction (such as the comparative method) were developed as a result. PIE is hypothesized to have been spoken as a single language from approximately 4500 BCE to 2500 BCE during the Late Neolithic to Early Bronze Age, though estimates vary by more than a thousand years. According to the prevailing Kurgan hypothesis, the original homeland of the Proto-Indo-Europeans may have been in the Pon ...

Welsh Language
Welsh ( or ) is a Celtic languages, Celtic language of the Brittonic languages, Brittonic subgroup that is native to the Welsh people. Welsh is spoken natively in Wales by about 18% of the population, by some in England, and in (the Welsh colony in Chubut Province, Argentina). It is spoken by smaller numbers of people in Canada and the United States descended from Welsh immigrants, within their households (especially in Nova Scotia). Historically, it has also been known in English as "British", "Cambrian", "Cambric" and "Cymric". The Welsh Language (Wales) Measure 2011 gave the Welsh language official status in Wales. Welsh and English are ''de jure'' official languages of the Senedd (the Welsh parliament), with Welsh being the only ''de jure'' official language in any part of the United Kingdom, with English being merely ''de facto'' official. According to the 2021 United Kingdom census, 2021 census, the Welsh-speaking population of Wales aged three or older was 538,300 ( ...

Common Brittonic
Common Brittonic (; ; ), also known as British, Common Brythonic, or Proto-Brittonic, is a Celtic language historically spoken in Britain and Brittany from which evolved the later and modern Brittonic languages. It is a form of Insular Celtic, descended from Proto-Celtic, a theorized parent language that, by the first half of the first millennium BC, was diverging into separate dialects or languages. Pictish is linked, most probably as a sister language or a descendant branch. Evidence from early and modern Welsh shows that Common Brittonic was significantly influenced by Latin during the Roman period, especially in terms related to the church and Christianity. By the sixth century AD, the languages of the Celtic Britons were rapidly diverging into Neo-Brittonic: Welsh, Cumbric, Cornish, Breton, and possibly the Pictish language. Over the next three centuries, Brittonic was replaced by Scottish Gaelic in most of Scotland, and by Old English (from which descend M ...

Hydronym
A hydronym (from , , "water" and , , "name") is a type of toponym that designates a proper name of a body of water. Hydronyms include the proper names of rivers and streams, lakes and ponds, swamps and marshes, seas and oceans. As a subset of toponymy, a distinctive discipline of ''hydronymy'' (or ''hydronomastics'') studies the proper names of all bodies of water, the origins and meanings of those names, and their development and transmission through history. Classification by water types Within the onomastic classification, main types of hydronyms are (in alphabetical order): * helonyms: proper names of swamps, marshes and bogs * limnonyms: proper names of lakes and ponds * oceanonyms: proper names of oceans * pelagonyms: proper names of seas and maritime bays * potamonyms: proper names of rivers and streams Linguistic phenomena Often, a given body of water will have several entirely different names given to it by different peoples living along its shores.
