as in a jockstrap came first when compared to jock
as in an athlete. But before both, jock was a euphemism for the male genitals.
So first you had jock
, the male genitals. Then you had the jockstrap
, the strap that held the male genitals. Then you had the jock
, the athlete, who wore the jockstrap, and got the nickname jock
from shortening the name of the jockstrap that he wore.
Speaking of nickname, actually the original was ickname
(originally spelled eke) meant also
. So a name that you were also called was your ickname
. But when you say something like "An ickname of John is Jack." It was unclear if the n
belonged to An
. Over time, it moved off of An
and became attached to ickname
. And we got nickname
. Your also-name...or should I say, n-aslo-name? ...
Edit: I gotta learn not to bother to answer these threads.
