Attested: (1) AI iter 1 Derventione
(2) RC Derventione and Dorvantium
(3) ND Derventione
Where: (1) Stamford Bridge Roman fort(?) at SE715555 by the Yorkshire river Derwent. Not at Malton!
(2) Papcastle Roman fort and settlement at NY10963149 by the Cumbria river Derwent.
(3) could be the same as either of the other two; R&S favoured Yorkshire, but Cumbria seems more likely.
Name origin: An etymology based on *daru-/*deru- ‘(oak)tree’ has been proposed for the rivers Derwent (and similar) since at least Ekwall (1928:121-3), but is less convincing than PIE *der- ‘to run’, especially in light of Sanskrit dravati ‘to flow’. The letters NT tend to mark verbal present participles, and Latin deruo ‘to fall down’ would have had a participle deruens, deruentis (where U and V were the same letter in Roman times), appropriate for rivers descending from higher ground.
Notes: RC also mentions Derbentione (probably Derby). Notice how RC mentions both Derventione as a place and Dorvantium as one of the estuaries that were significant harbours in Roman times.
