It carries the Oxford Ring Road , part of the A423 road , across the Thames on the reach between Sandford Lock and Iffley Lock . The bridge was built in the 1960s and opened to road traffic in 1965 when the section of the ring road between South Hinksey and Heyford Hill was opened. It is
172-599: A "plausible vector for the spread of early Celtic languages into Britain". There was much less inward migration during the Iron Age, so it is likely that Celtic reached Britain before then. Barry Cunliffe suggests that a Goidelic branch of Celtic may already have been spoken in Britain, but that this middle Bronze Age migration would have introduced the Brittonic branch. Brittonic languages were probably spoken before
258-473: A Celtic word that might mean 'painted ones' or 'tattooed folk', referring to body decoration. Knowledge of the Brittonic languages comes from a variety of sources. The early language's information is obtained from coins, inscriptions, and comments by classical writers as well as place names and personal names recorded by them. For later languages, there is information from medieval writers and modern native speakers, together with place names. The names recorded in

430-595: A common ancestral language termed Brittonic , British , Common Brittonic , Old Brittonic or Proto-Brittonic , which is thought to have developed from Proto-Celtic or early Insular Celtic by the 6th century BC. A major archaeogenetics study uncovered a migration into southern Britain in the middle to late Bronze Age , during the 500-year period 1,300–800 BC. The newcomers were genetically most similar to ancient individuals from Gaul . During 1,000–875 BC, their genetic markers swiftly spread through southern Britain, but not northern Britain.

The same structure is also found in modern Dutch ( Ik ben aan het werk ), alongside other structures (e.g. Ik zit te werken , lit. 'I sit to working'). These parallel developments suggest that
774-738: A revival in Cornish has led to an increase in speakers of that language. Cumbric and Pictish are extinct, having been replaced by Goidelic and Anglic speech. The Isle of Man and Orkney may also have originally spoken a Brittonic language, but this was later supplanted by Goidelic on the Isle of Man and Norse on Orkney. There is also a community of Brittonic language speakers in Y Wladfa (the Welsh settlement in Patagonia ). The names "Brittonic" and "Brythonic" are scholarly conventions referring to
860-571: A revival movement has more recently created small numbers of new speakers. Also notable are the extinct language Cumbric , and possibly the extinct Pictish . One view, advanced in the 1950s and based on apparently unintelligible ogham inscriptions, was that the Picts may have also used a non- Indo-European language. This view, while attracting broad popular appeal, has virtually no following in contemporary linguistic scholarship. The modern Brittonic languages are generally considered to all derive from

However, some common words such as monadh = Welsh mynydd , Cumbric monidh are particularly evident. The Brittonic influence on Scots Gaelic is often indicated by considering Irish language usage, which is not likely to have been influenced so much by Brittonic. In particular,

The river's name has always been pronounced with a simple t /t/ ; the Middle English spelling was typically Temese and the Brittonic form Tamesis . A similar spelling from 1210, "Tamisiam" (the accusative case of "Tamisia"; see Kingston upon Thames § Early history ),
1462-572: Is derived from the Brittonic name for the river, Tamesas (from * tamēssa ), recorded in Latin as Tamesis and yielding modern Welsh Tafwys "Thames". The name element Tam may have meant "dark" and can be compared to other cognates such as Russian темно ( Proto-Slavic * tĭmĭnŭ ), Lithuanian tamsi "dark", Latvian tumsa "darkness", Sanskrit tamas and Welsh tywyll "darkness" and Middle Irish teimen "dark grey". The origin

With its waters varying from freshwater to almost seawater, the Thames supports a variety of wildlife and has a number of adjoining Sites of Special Scientific Interest , with the largest being in the North Kent Marshes and covering 20.4 sq mi (5,289 ha). According to Mallory and Adams, the Thames, from Middle English Temese ,

The river's position has put it at the centre of many events in British history, leading to it being described by John Burns as "liquid history". Two broad canals link the river to other rivers: the Kennet and Avon Canal ( Reading to Bath ) and
1720-697: Is found in Magna Carta . The Thames through Oxford is sometimes called the Isis . Historically, and especially in Victorian times, gazetteers and cartographers insisted that the entire river was correctly named the Isis from its source down to Dorchester on Thames and that only from this point, where the river meets the Thame and becomes the "Thame-isis" (supposedly subsequently abbreviated to Thames) should it be so called. Ordnance Survey maps still label
1806-613: Is probable that at the start of the Post-Roman period, Common Brittonic was differentiated into at least two major dialect groups – Southwestern and Western. (Additional dialects have also been posited, but have left little or no evidence, such as an Eastern Brittonic spoken in what is now the East of England .) Between the end of the Roman occupation and the mid-6th century, the two dialects began to diverge into recognizably separate varieties,

During the next few centuries, in much of Britain the language was replaced by Old English and Scottish Gaelic , with the remaining Common Brittonic language splitting into regional dialects, eventually evolving into Welsh , Cornish , Breton , Cumbric , and probably Pictish . Welsh and Breton continue to be spoken as native languages, while

Some writers use "British" for the language and its descendants, although, due to the risk of confusion, others avoid it or use it only in a restricted sense. Jackson, and later John T.

Richard Coates suggests that while the river was as a whole called the Thames, part of it, where it was too wide to ford, was called * (p)lowonida . This gave the name to a settlement on its banks, which became known as Londinium , from the Indo-European roots * pleu- "flow" and * -nedi "river" meaning something like

Jackson noted by that time that "Brythonic" had become a dated term: "of late there has been an increasing tendency to use Brittonic instead." Today, "Brittonic" often replaces "Brythonic" in the literature. Rudolf Thurneysen used "Britannic" in his influential A Grammar of Old Irish , although this never became popular among subsequent scholars. Comparable historical terms include

Western Herefordshire continued to speak Welsh until

Substantial numbers of Britons certainly remained in the expanding area controlled by Anglo-Saxons , but over the fifth and sixth centuries they mostly adopted the Old English language and culture. The Brittonic languages spoken in what are now Scotland , the Isle of Man , and England began to be displaced in
3784-816: The Brittonic languages were displaced is that of toponyms (place names) and hydronyms (names of rivers and other bodies of water). There are many Brittonic place names in lowland Scotland and in the parts of England where it is agreed that substantial Brittonic speakers remained (Brittonic names, apart from those of the former Romano-British towns, are scarce over most of England). Names derived (sometimes indirectly) from Brittonic include London , Penicuik , Perth , Aberdeen , York , Dorchester , Dover , and Colchester . Brittonic elements found in England include bre- and bal- for 'hill', while some such as co[o]mb[e] (from cwm ) for 'small deep valley' and tor for 'hill, rocky headland' are examples of Brittonic words that were borrowed into English. Others reflect
3870-496: The English progressive is not necessarily due to Celtic influence; moreover, the native English development of the structure can be traced over 1000 years and more of English literature. Some researchers (Filppula, et al., 2001) argue that other elements of English syntax reflect Brittonic influences. For instance, in English tag questions , the form of the tag depends on the verb form in the main statement ( aren't I? , isn't he? , won't we? , etc.). The German nicht wahr? and
3956-641: The French n'est-ce pas? , by contrast, are fixed forms which can be used with almost any main statement. It has been claimed that the English system has been borrowed from Brittonic, since Welsh tag questions vary in almost exactly the same way. Far more notable, but less well known, are Brittonic influences on Scottish Gaelic , though Scottish and Irish Gaelic, with their wider range of preposition-based periphrastic constructions, suggest that such constructions descend from their common Celtic heritage. Scottish Gaelic contains several P-Celtic loanwords, but, as there

In London, the water is slightly brackish with sea salt, being a mix of sea and fresh water. This part of the river is managed by the Port of London Authority . The flood threat here comes from high tides and strong winds from
4214-492: The Roman invasion throughout most of Great Britain , though the Isle of Man later had a Goidelic language, Manx . During the period of the Roman occupation of what is now England and Wales (AD 43 to c. 410 ), Common Brittonic borrowed a large stock of Latin words, both for concepts unfamiliar in the pre-urban society of Celtic Britain such as urbanization and new tactics of warfare, as well as for rather more mundane words which displaced native terms (most notably,

The Brittonic branch is also referred to as P-Celtic because linguistic reconstruction of the Brittonic reflex of the Proto-Indo-European phoneme * kʷ is p as opposed to Goidelic k . Such nomenclature usually implies acceptance of the P-Celtic and Q-Celtic hypothesis rather than the Insular Celtic hypothesis because the term includes certain Continental Celtic languages as well.

Since the early 20th century this distinction has been lost in common usage outside of Oxford, and some historians suggest the name Isis is nothing more than a truncation of Tamesis , the Latin name for the Thames.

In descending order, non-related tributaries of the non-tidal Thames, with river status, are the Churn , Leach , Cole , Ray , Coln , Windrush , Evenlode , Cherwell , Ock , Thame , Pang , Kennet , Loddon , Colne , Wey and Mole . In addition, there are occasional backwaters and artificial cuts that form islands, distributaries (most numerous in
6278-596: The river, covering three counties . In non-administrative use, the river's name is used in those of Thames Valley University , Thames Water , Thames Television , publishing company Thames & Hudson , Thameslink (north–south rail service passing through central London ) and South Thames College . An example of its use in the names of historic entities is the Thames Ironworks and Shipbuilding Company . Marks of human activity, in some cases dating back to Pre-Roman Britain , are visible at various points along
6364-456: The river, while some islands, e.g. Thorney Island , formed over the ages. The northern tip of the ancient parish of Lambeth , for example, was marshland known as Lambeth Marshe , but it was drained in the 18th century; the street names Lower Marsh and Upper Marsh preserve a memory. Until the middle of the Victorian era, malaria was commonplace beside the River Thames, even in London, and
6450-467: The river. These include a variety of structures connected with use of the river, such as navigations, bridges and watermills , as well as prehistoric burial mounds . The lower Thames in the Roman era was a shallow waterway winding through marshes. But centuries of human intervention have transformed it into a deep tidal canal flowing between 200 miles of solid walls; these defend a floodplain where 1.5 million people work and live. A major maritime route
6536-611: The sandbank was a major hazard for shipping coming in and out of London, in 1732 it received the world's first lightship . This became a major landmark, and was used as an assembly point for shipping. Today it is marked by Sea Reach No. 1 Buoy. The River Thames contains over 80 islands ranging from the large estuarial marshlands of the Isle of Sheppey and Canvey Island to small tree-covered islets like Rose Isle in Oxfordshire and Headpile Eyot in Berkshire. They are found all
6622-541: The south coast), and the Wilts & Berks Canal . Rowing and sailing clubs are common along the Thames, which is navigable to such vessels. Kayaking and canoeing also take place. Major annual events include the Henley Royal Regatta and the Boat Race , while the Thames has been used during two Summer Olympic Games : 1908 ( rowing ) and 1948 ( rowing and canoeing ). Safe headwaters and reaches are
6708-498: The theory of a more significant Brittonic influence than is widely accepted point out that many toponyms have no semantic continuation from the Brittonic language. A notable example is Avon which comes from the Celtic term for river abona or the Welsh term for river, afon , but was used by the English as a personal name. Likewise the River Ouse, Yorkshire , contains the Celtic word usa which merely means 'water' and
6794-607: The two branches of the Insular Celtic languages; the other is Goidelic . It comprises the extant languages Breton , Cornish , and Welsh . The name Brythonic was derived by Welsh Celticist John Rhys from the Welsh word Brython , meaning Ancient Britons as opposed to an Anglo-Saxon or Gael . The Brittonic languages derive from the Common Brittonic language, spoken throughout Great Britain during
6880-705: The way from Fiddler's Island in Oxfordshire to the Isle of Sheppey in Kent. Some of the largest inland islands, for example Formosa Island near Cookham and Andersey Island at Abingdon, were created naturally when the course of the river divided into separate streams. In the Oxford area the river splits into several streams across the floodplain ( Seacourt Stream , Castle Mill Stream , Bulstake Stream and others), creating several islands ( Fiddler's Island , Osney and others). Desborough Island , Ham Island at Old Windsor and Penton Hook Island were artificially created by lock cuts and navigation channels. Chiswick Eyot
6966-412: The western part. The area is among the driest in the United Kingdom. Water resources consist of groundwater from aquifers and water taken from the Thames and its tributaries, much of it stored in large bank-side reservoirs . The Thames itself provides two-thirds of London's drinking water, while groundwater supplies about 40 per cent of public water supplies in the overall catchment area. Groundwater
7052-464: The word for 'fish' in all the Brittonic languages derives from the Latin piscis rather than the native * ēskos – which may survive, however, in the Welsh name of the River Usk , Wysg ). Approximately 800 of these Latin loan-words have survived in the three modern Brittonic languages. Pictish may have resisted Latin influence to a greater extent than the other Brittonic languages. It
7138-580: The year, while those at Thames Head are seasonal (a winterbourne ). With a length of 215 mi (346 km), the Thames is the longest river entirely in England. (The longest river in the United Kingdom, the Severn , flows partly in Wales .) However, as the River Churn, sourced at Seven Springs, is 14 mi (23 km) longer than the section of the Thames from its traditional source at Thames Head to
7224-479: Was built at the site of London Bridge . London Bridge is now used as the basis for published tide tables giving the times of high tide . High tide reaches Putney about 30 minutes later than London Bridge, and Teddington about an hour later. The tidal stretch of the river is known as "the Tideway ". Tide tables are published by the Port of London Authority and are available online. Times of high and low tides are also posted on Twitter. The principal tributaries of
7310-463: Was frequently lethal. Some cases continued to occur into the early 20th century. Draining of the marshes helped with its eradication, but the causes are complex and unclear. The East End of London , also known simply as the East End , was the area of London east of the medieval walled City of London and north of the River Thames, although it is not defined by universally accepted formal boundaries;
7396-617: Was subject to minor redefining and widening of the main channel around Oxford, Abingdon and Marlow before 1850, when further cuts to ease navigation reduced distances further. Molesey faces Hampton , and in Greater London the Thames passes Hampton Court Palace , Surbiton , Kingston upon Thames , Teddington , Twickenham , Richmond (with a famous view of the Thames from Richmond Hill), Syon House , Kew , Brentford , Chiswick , Barnes , Hammersmith , Fulham , Putney , Wandsworth , Battersea and Chelsea .
