The word is not found anywhere else and remains problematic. Fr Voc, which glosses the word as 'erwyngge', derives its information from the Bibbesworth text. However, the text, as it is presented in the Owen edition, has an ambiguity about its Middle English glosses, and it appears that glaue may also have been glossed as 'filth', while the gloss 'lytyl herewyg' may refer to enemi, later in the same line.
