Etymology
The name ''Cheviot'', which was first documented in 1181 as ''Chiuiet'', is probably of Common Brittonic, Brittonic origin. The name involves the element ''*ceμ-'', meaning "a ridge", and the nominal suffix ''-ed'', which in place-names can mean "having the quality of".

Access
Other than the route via the Pennine Way, most routes up the Cheviot start from the Harthope Burn side to the northeast, which provides the nearest access by road. The summit is around from the road-end at Langleeford; across the valley to the east is the rounded peak of Hedgehope. There are routes following the ridges above either side of the valley, and a route that sticks to the valley floor until it climbs to the summit of the Cheviot from the head of the valley.
Although the Pennine Way does a out-and-back detour to the Cheviot, many walkers who come this way omit it, since the stage (the most northerly) is long.
