On the One-Breasted Amazon
"The amazon thing? It's bullshit, a convoluted nightmare of folk tales and bad etymology lead to (Privative) a- (Without) and -mazos (Breast).

Amazons in art and in Greek accounts are depicted as having both breasts, and an alternative etymology suggests it may have been (Intensive) a- and -Mazos, meaning "full-breasted"."
