- "Nilpotentcy" describes Dan Quayle's chances for the 1996 presidential
- elections.
-
- To decide between nilpotency and nilpotence I grepped for "potenc" in
- some 300 technical papers I had online and found 37 occurrences of
- "idempotenc..". Generally "idempotency" was preferred, only a couple
- of authors used "idempotence." (I confess to being one of them.)
-
- I then browsed around in Webster's New World Dictionary, Funk and
- Wagnall's Standard College Dictionary, and the Oxford English
- Dictionary (unabridged, 16,464 pages). None had either "idempotent" or
- "nilpotent". However all three explained "-ence" vs. "-ency". F&W
- (US) and OED (UK) agreed that "-ency" was used for static qualities and
- "-ence" for dynamic (cf. state of emergency vs. act of emergence---if
- you disagree write to the dictionaries, not me), whereas Webster did
- not draw this distinction and gave the same meaning for both endings.
- On the other hand both F&W and Webster gave "impotence" as the primary
- usage and "impotency" as a secondary equivalent. But so as to be truly
- democratic in such matters they both reversed this for "potence" vs.
- "potency", preferring the latter.
-
- This is enough ammunition for any mercenary willing to argue either
- side, almost guaranteeing a win against a more lightly armed opponent.
- And you should have no difficulty arguing either side of whether
- nilpotence is a static or dynamic quality.
-
- As for me I'm going to stick to "idempotence" and "nilpotence," which
- somehow sound nicer to my ear.
