hey i was checking out some big/confusing words before and i was wondering-what are the biggest/most confusing words you know or just some words that are like-- if you used them in english at school you would get an A+

i think the biggest english word is either antidisestablishmentarianism or Floccinaucinihilipilification (both of them are spelled right XD)
the second one im not so sure its actually english
