Note 21 — Chapter X · Difficulties of the Folklorist

The Book of Ỻan Dáv has an old form Cinust for an earlier Cingust or Congust. The early Brythonic nominative must have been Cunogústu-s and the early Goidelic Cúnagusu-s, and from the difference of accentuation come the o of Conghus, Connws, and the y of the Welsh Cynwst: compare Irish Fergus and Welsh Gurgúst, later Gu̯rúst (one syllable), whence Grwst, finally the accented rwst of Ỻanrwst, the name of a small town on the river Conwy. Moreover the accentuation Cúnogusi is the reason why it was not written Cunogussi: compare Bárrivendi and Véndubari in one and the same inscription from Carmarthenshire. ↑
