This isn't an actual entry. It's only an annoyance with the OED's definition of "geruda":
Of an escutcheon: Divided into or having gyrons; gyronny of eight, having eight gyrons, i.e. each quarter divided diagonally by lines meeting in the fesse-point.
I just want to extend my thanks and appreciation to the OED for the absolute uselessness of that definition...bah, ugh, fie or something.
