When I search for the word overseee in Google books, almost all links are typos of the verb to oversee, which in itself looks amazing to me. (Books rarely have such silly typos.) And only one reference among hundreds there is for the meaning I expected. (see subject)
So does the word overseee actually mean the opposite of overseer?
And the secondary question is what makes people to mistype this particular word so frequently? I search like that a lot, and usually a search for some typo doesn't fetch that many results like that. OED and Merriam-Webster don't have this word.
