Roman 'culture words' seem to occur in the later British language, and some at least of these may be traceable to the Roman occupation of the island.

Roman military terms appear, if scantily.

Roman inscriptions are occasionally set up.

The Romanization of Britain was plainly no mere interlude, which passed without leaving a mark behind.[1] But it was crossed by two hostile forges, a Celtic revival and an English invasion.
[Footnote 1: Much of the ornamentation used by post-Roman Celtic art comes from Roman sources, in particular the interlaced or plaitwork, which has been well studied by Mr.Romilly Allen.

But how far it was borrowed from Romano-British originals and how far from similar Roman-provincial work on the Continent, is not very clear.
