Nice thread.
Just want to chime in on
regimen vs
regime.
I always say regimen. But, and I apologize in advance for any gag reflex my next statement may trigger,
regime is now a synonym for regimen. I know, I know. But that doesn't bother me as much as "irregardless" being in the dictionary, whether informal or not.
OK, about regime:
The first definition of
regime in Merriam Webster Dictionary is
regimen (That link takes you to the reference site that shows this)
Encarta gives the fourth definition of
regime as "an established system or way of doing things".
WordNet give the second meaning of the word
regime as
regimen.
And you can find more such definitions in:
American Heritage Dictionary of the English Language

Maybe it's just American English that uses them interchangeably coz Collins, Longman, and Cambridge Dictionaries online don't seem to think that regime = regimen like all those other sites above do.
