missaying

And therefore all the missaying that ye missaid me furthered me in my battle, and caused me to think to show and prove myself at the end what I was.

Stories of King Arthur and His Knights Retold from Malory's "Morte dArthur" U. Waldo Cutler

And after he had cast his books into the sea he returned, and holding his feet said: O thou deliverer of souls, receive me penitent, and him that hath sustained till now missaying of thee.

The Golden Legend, vol. 4 1230-1298 1900

And therefore all the missaying that ye missaid me furthered me in my battle, and caused me to think to show and prove myself at the end what I was; for peradventure though I had meat in King Arthur's kitchen, yet I might have had meat enough in other places, but all that I did it for to prove and assay my friends, and that shall be known another day; and whether that I be a gentleman born or none, I let you wit, fair damosel, I have done you gentleman's service, and peradventure better service yet will I do or I depart from you.
