G gleann + ?
‘Glen or valley of ?’; there is an alarming amount of variation in the early forms. However, the name is known locally, as Glencortas, pointing to -cortas as the correct form. The name is certainly a Gaelic coining, and it is possible that the second element is G coirthe ‘standing stone, pillar stone’, with the G locational suffix –as. If so, the eponymous stone seems to be no longer extant.
The eponymous valley, on the other hand, is still clearly identifiable, as that through which the road from Lumquhat to Rossie passes. The above NGR is of roughly the mid-point.
