Susan, We done you wrong. But there really isn’t that much to tell (at least about the non-sexual ‘booty’) and what there is ain’t that exciting.
The Oxford Dictionary of Word Origins
BOOTY [late Middle English] ‘Booty’ first referred to the plunder that was acquired in common and was then divided; the source is Middle Low German ‘bute,’ ‘buite,’ exchange, distribution, but earlier details of the origin are uncertain. The notion of sharing gradually became a less prominent feature of the meaning.
The Barnhart Concise Dictionary of Etymology
BOOTY noun 1474 ‘boyte’; later ‘buty’(1491), perhaps developed from earlier ‘boti,’ adjective profiting by plunder (probably about 1439) or from ‘bottyne’ booty (about 1450); borrowed from Old French ‘butin’ booty, and directly from Middle Low German ‘bute,’ ‘buite’ exchange, barter, booty; or borrowed from earlier Dutch ‘buyt,’ ‘buet’ booty.
As for the relationship of 'pirate' booty, and the ‘buttocks/sexual' kind, I see very little.
Oxford English Dictionary
[Probably an altered form of BOTTY noun.; compare BATTY (a person's buttocks; the backside.) Perhaps influenced by BOOTY noun Plunder, gain, or profit acquired in common and destined to be divided among the winners.]
From the above, I guess the only relationship I see between the two kinds of BOOTY
is that they are spelled the same.
