mynydd

mynyddoedd (plural)

From Proto-Celtic *korks; related to Cornish kors (“reeds”), Breton korz (“reeds”), and further to Old Irish curchais (“reedbed”), and perhaps to Latin cārex (“sedge”). Cameron connects Proto-Indo-European *(s)kerbʰ- (“to turn (around), wind”), on the basis of Latin scirpus, reasoning that reeds and bulrushes were formerly used to make ropes.

paith

peithiau (plural)
paith
baith (soft)
mhaith
phaith

According to the GPC, a corruption from earlier diffaith (“derelict, desolate”), itself a borrowing from Latin defectus (“emptiness, absence”).
