  • Means 'powerful' in French, right? Doesn't look or sound powerful to me. It looks like the least powerful word I can think of, except maybe 'pantuflas' (the Spanish word for 'slippers'). It looks more like 'piss-ant' than anything, and we all know those aren't powerful.

  • @ TheSarahEffect: Sorry to hear about the bad experience with your English teacher, who seems to feel it's her/his job to limit rather than expand your vocabulary. I wonder if your teacher knows what "esoteric" means; I certainly wouldn't use it to describe "puissant" – erudite maybe, but not "esoteric".

    I pronounce it more or less as you and Chained_bear do: two syllables: PWISS-ent (that "e" is a schwa). I think the French pronunciation would be: pü-i-SÃ, where the "ü" stands for that narrow, unrounded front-of-the-mouth "u", the "i" is as in machine, and the "ã" is a nasal "ah". But when you're speaking English, I strongly recommend using English pronunciations.

  • it's not esoteric, just awkward (which I suspect the teacher tried to find a high-falutin' synonym for and failed). I can't see a justified use of puissant in any paper after the 18th century.
