Scour? for Exploitation?
Who would have thought?
I definitely thought it was spelled scower. My bad. And I definitely can't use it in my essay, so fml.
Origins are always fun...
[Middle English scouren, from Middle Dutch scūren, from Old French escurer, from Late Latin excūrāre, to clean out : Latin ex-, ex-, Late Latin cūrāre, to clean (from Latin, to take care of, from cūra, care; see cure).]

Sorry, I just enjoy my unusual words. Like disconcerted, another treasure. Why do I have to learn a foreign language when there are so many brilliant words in English that surely need further exploitation.

On that note...
exploit (n.)
1393, from O.Fr. esploit, a very common v., used in senses of "action, deed, profit, achievement," from L. explicitum "a thing settled, ended, displayed," neut. of explicitus, pp. of explicare "unfold" (see explicit). Sense evolution is from "unfolding" to "bringing out" to "having advantage" to "achievement." The v. (M.E. espleiten, esploiten) meant "to accomplish;" the sense of "use selfishly" first arising 1838, as an adoption of Fr. exploiter.

A word victim of obvious jealousy. People have brought on a modern negative connotation to this one.
