Note 113b — THE GODODIN.
John Williams translation
If “ffosawd” ever bears the meaning assigned to it by Dr. Pughe, it must have derived it from the practise of fighting in the fosse of a camp, (which would be peculiarly gashing) for on his own showing the word has no other etymon than that of “ffos,” a ditch, a trench. From the same root Merddin gives it the sense of burial—defossio.
