Brace yourself. There are many. This is all I ever think about when I have insomnia, or in this case, a TOK draft D. Most of these are courtesy of Christopher Hitchens op-eds...

• paroxysm
  • sudden outburst
• weltschmerz
  • if you know me well enough to be creeping this, I have probably explained this one to you many times
• sycophant
  • self-seeking flatterer
• pith
  • the white stuff around an orange
• aquitard
  • the base of an aquifer
• ordure
  • shit.
• dais
  • a raised platform
• ubiquity
  • commonplace
  • Has lovely calligraphy. "Ubiqu" looks almost like an odd function.
• beautiful
  • I know, how boring. This word depends entirely on context. It has to be the right person, describing the right thing, with conviction. Softly, about something that's not so tired - there's plenty of beautiful vistas and people in this world. I want beautiful ideas, beautiful theorems, beautiful industrial parks!
• antediluvian
  • literally "before the flood", decrepit and ancient
• celestial
  • stars and stuff
• fluvial
  • pertaining to a river
• hi
  • an informal greeting. Best when preceding "there," as in "hi there."
• defenestrate
  • exit via window
• cursory
  • brief
• farce
  • a foolish show
  • Like beautiful, it's a word that's best when applied to something less obvious. i.e. "Henrieta, your omelette is pure farce. Watch and learn." or "Bio is farce."
• iconoclast
  • a breaker of images
  • Only thing I learned from Thus Spake Zarathustra
