Etymology

Cf. also Glencoyne Wood (infra ). Ekwall (RN 178) derives this from Brit  glennos (Welsh  glyn ) 'glen' and a r.n. related to the Gaulish r.n. Kaivós (Ptolemy) and OIr  caín 'beautiful', but Förster, Themse 577 and Jackson 328, do not regard the substitution of OE  *cōn - for PrWelsh  *coin - (Brit  *caino -) as possible, and in addition Jackson points out that no such word is known in British or the Brythonic dialects. The dialect pronunciation [gleŋˈkiun] points to a ME  -cōne and most other spellings in -kune and -coyne can be accepted as variants of this; -caine and some of the later antiquarian spellings -kwent , etc. are not easily explained as variants of -cōne .Possibly Welsh  cawn 'reed-grass' might be considered as the second el.'Reed valley'.
