I use to be very interested in fencing vocabulary. Right up to the point where I saw that in USFCA that a couple of words had two totally different meanings and they listed both of them. Reprise and remise have a standard definition and two others for referees. As if things weren't confusing enough.
A while back I started writing fencing vocabulary words on a dry erase board hanging on a wall at the Charlotte club. It soon became apparent to me that the words I wrote (That the kids would not know.) were pretty much antiquated fencing moves. No point bothering to do it. I guess they know enough.)
Still, I often become dismayed when I hear some kids talk. For example: Disengage. To disengage, you must first be engaged. It bothers me. Just not enough to say anything. Thanks to Alex Beguinet, I also cringe when I hear "counter parry.". I will not even get into that one.
