How come the msq keeps using big words?

[Gula]

You do not need to be an English major to understand the "big words". You just need to be normally literate and have at least some basic education - the vocabulary used is not that unusual. Oh, and one must not be a troll - I fear that is your problem.
Urianger speaks like he does because he has read far too many old books and picked up his speech patterns from those.

FYI, "puissant" means "powerful"

I remember (native English speakers) complaining about Alisae saying "buoyant" when referring to Alphinaud's inability to swim. People just can't seem to use dictionaries anymore, and apparently missed out on context clues from 5th grade.

I admittedly don't know every single word that's used because of ye olde English but I think it should be normal to seek the knowledge instead of wallow in indolence and ignorance.
