geoffreycaveney's Middle English theory

[davidjackson]

However, I wish to point out that every word in "fous", "irour thee#", "fob sib isib", and "York/#roy" appears in the Middle English Compendium, so I have not had to rely on Anglo-French / Anglo-Norman to explain any words yet.

Roy is French, not English - the borrowed word imported into middle English is spelt Roi/e or even Roye. But I will admit there is more than enough ambiguity in the spelling to allow for your interpretation.
Roy appears to have been a common enough name at the time.

Interestingly enough, the dictionary gives three meanings for Roi/e, the middle one hadn't occurred to me before.

(a) A king; (b) ?a man, fellow; © as name.
