62-563: Greenwich Pier is on the south bank of the River Thames in Greenwich , London . It was built in 1836 to cater for the many paddle steamers that brought visitors on day trips to Greenwich from London further up river. At the time, London's urban area did not extend as far out as Greenwich. The pier is currently owned by London River Services and is used by various river operators, running public cruise services to and from Central London. It
124-532: A common parent language . Because language change can have radical effects on both the sound and the meaning of a word, cognates may not be obvious, and it often takes rigorous study of historical sources and the application of the comparative method to establish whether lexemes are cognate. Cognates are distinguished from loanwords , where a word has been borrowed from another language. The English term cognate derives from Latin cognatus , meaning "blood relative". An example of cognates from
186-617: A common origin, but which in fact do not. For example, Latin habēre and German haben both mean 'to have' and are phonetically similar. However, the words evolved from different Proto-Indo-European (PIE) roots: haben , like English have , comes from PIE *kh₂pyé- 'to grasp', and has the Latin cognate capere 'to seize, grasp, capture'. Habēre , on the other hand, is from PIE *gʰabʰ 'to give, to receive', and hence cognate with English give and German geben . Likewise, English much and Spanish mucho look similar and have
248-552: A network of creeks. Lying below sea level, it is prone to flooding at exceptional tides, but has nevertheless been inhabited since Roman times. The usually quoted source of the Thames is at Thames Head (at grid reference ST980994 ). This is about 1.5 mi (2.4 km) north of the village of Kemble in southern Gloucestershire , near the town of Cirencester , in the Cotswolds . However, Seven Springs near Cheltenham , where

Running through some of the drier parts of mainland Britain and heavily abstracted for drinking water, the Thames' discharge is low considering its length and breadth: the Severn has a discharge almost twice as large on average despite having a smaller drainage basin . In Scotland ,

A true cognate of much is the archaic Spanish maño 'big'. Cognates are distinguished from other kinds of relationships. An etymon , or ancestor word, is the ultimate source word from which one or more cognates derive. In other words, it

After the river took its present-day course, many of the banks of the Thames Estuary and the Thames Valley in London were partly covered in marshland , as was the adjoining Lower Lea Valley .

Islands of historical interest include Magna Carta Island at Runnymede , Fry's Island at Reading, and Pharaoh's Island near Shepperton. In more recent times Platts Eyot at Hampton was the place where Motor Torpedo Boats (MTB)s were built, Tagg's Island near Molesey was associated with

Groundwater is vulnerable to surface pollution, especially in highly urbanised areas. Brooks, canals and rivers, within an area of 3,842 sq mi (9,951 km ), combine to form 38 main tributaries feeding the Thames between its source and Teddington Lock . This

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 ),

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
806-678: 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

However, beyond paradigms, morphosyntax is often excluded in the assessment of cognacy between words, mainly because structures are usually seen as more subject to borrowing. Still, very complex, non-trivial morphosyntactic structures can rarely take precedence over phonetic shapes to indicate cognates. For instance, Tangut ,
992-452: Is responsible for managing the flow of water to help prevent and mitigate flooding, and providing for navigation: the volume and speed of water downstream is managed by adjusting the sluices at each of the weirs and, at peak high water, levels are generally dissipated over preferred flood plains adjacent to the river. Occasionally, flooding of inhabited areas is unavoidable and the agency issues flood warnings. Due to stiff penalties applicable on

Kenneth H. Jackson proposed that the name of

Descendants are words inherited across a language barrier, coming from a particular etymon in an ancestor language. For example, Russian мо́ре and Polish morze are both descendants of Proto-Slavic * moře (meaning sea ). A root

Similar to the distinction between etymon and root , a nuanced distinction can sometimes be made between a descendant and a derivative . A derivative is one of the words which have their source in a root word, and were at some time created from the root word using morphological constructs such as suffixes, prefixes, and slight changes to

In these circumstances, tidal effects can be observed upstream to the next lock beside Molesey weir , which is visible from the towpath and bridge beside Hampton Court Palace .

About 450,000 years ago, in the most extreme Ice Age of the Pleistocene , the Anglian , the furthest southern extent of the ice sheet reached Hornchurch in east London, the Vale of St Albans, and the Finchley Gap .

Combined, this and other studies suggest that the Thames sea-level has risen more than 30 m during the Holocene at a rate of around 5–6 mm per year from 10,000 to 6,000 years ago. The rise of sea level dramatically reduced when
1426-514: The Churn (which feeds into the Thames near Cricklade ) rises, is also sometimes quoted as the Thames' source, as this location is farthest from the mouth and adds some 14 mi (23 km) to the river's length. At Seven Springs above the source is a stone with the Latin hexameter inscription "Hic tuus o Tamesine pater septemgeminus fons", which means "Here, O Father Thames, [is] your sevenfold source". The springs at Seven Springs flow throughout

Three further cross-basin canals are disused but are in various stages of reconstruction: the Thames and Severn Canal (via Stroud ), which operated until 1927 (to the west coast of England), the Wey and Arun Canal to Littlehampton , which operated until 1871 (to

From the west, it flows through Oxford (where it is sometimes called the Isis), Reading , Henley-on-Thames and Windsor . The Thames also drains the whole of Greater London . The lower reaches of the river are called the Tideway , derived from its long tidal reach up to Teddington Lock . Its tidal section includes most of its London stretch and has

Cognates need not have the same meaning, as they may have undergone semantic change as the languages developed independently. For example English starve and Dutch sterven 'to die' or German sterben 'to die' all descend from

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

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. Sculptures titled Tamesis and Isis by Anne Seymour Damer are located on the bridge at Henley-on-Thames , Oxfordshire (the original terracotta and plaster models were exhibited at

According to Mallory and Adams, the Thames, from Middle English Temese , 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".
