Editing River Tyne (section)

==Name and etymology==
Nothing definite is known of the origin of the designation ''Tyne'', nor is the river known by that name until the Saxon period: Tynemouth is recorded in Anglo-Saxon as {{lang|ang|Tinanmuðe}} (probably [[dative case]]). The ''Vedra'' on the [[Geographia (Ptolemy)|Roman map of Britain]] may be the Tyne, or may be the River Wear. Ptolemy's ''Tína'' could be a "misplaced reference" to either this river or the [[River Tyne, Scotland|Tyne]] in East Lothian.<ref name="cpns">{{cite book |last1=Watson |first1=W J |title=The History of the Celtic Placenames of Scotland |date=1926 |publisher=Irish Academic Press |location=Chippenham |page=51 }}</ref> There is a theory that {{lang|cel|*tīn}} was a word that meant "river" in the local [[Celtic languages|Celtic language]] or in a language spoken in England before the [[Celt]]s came: compare [[Tardebigge]].

A supposed [[pre-Celtic]] root ''*tei'', meaning 'to melt, to flow' has also been proposed as an etymological explanation of the Tyne and similarly named rivers,<ref name="bliton">{{Cite web|url=http://spns.org.uk/wp-content/uploads/2017/04/Alan_James_Brittonic_Language_in_the_Old_North_BLITON_Volume_II_Dictionary.pdf|title=The Brittonic Language in the Old North|website=Scottish Place Name Society|access-date=20 September 2018|archive-date=13 August 2017|archive-url=https://web.archive.org/web/20170813011121/http://spns.org.uk/wp-content/uploads/2017/04/Alan_James_Brittonic_Language_in_the_Old_North_BLITON_Volume_II_Dictionary.pdf|url-status=dead}}</ref> as has a [[Common Brittonic|Brittonic]] derivative of [[Proto-Indo-European language|Indo-European]] ''*teihx'', meaning 'to be dirty' ([[Welsh language|Welsh]] ''tail'', 'manure').<ref name="bliton" />
