uselessness It's science!! Oct 4, 2007
reesetee That'll learn me. Never enter uselessness' Land of Madeupical Etymologies without a map. Oct 4, 2007
uselessness On the contrary, there's a proven correlation. Science said it, history proved it, and I vouched for it. The connection is so real, etymology doesn't know about it yet. But it's pretty much indisputable fact amongst educated people. Some groups have even organized their own religions around this unwavering truth. You bet your buttons, you can totally bank on it.

reesetee Don't think so, arby, though I'm not positive. I think testy is from the Latin (and later, Italian and French) for "head"--so "headstrong," more or less.
There's an interesting word history for testis here. Oct 4, 2007
arby D'you suppose this is related to testes? (cf. testicular and the brilliant testiculate) Oct 4, 2007
