Here’s a list of words I screw up almost every time I try to spell them:

• Ubiquitous
• Silhouette
• Schizophrenia
• Curiosity

(Ironically, I got every one right on my first try here.) Curiosity is the surprising one, because it’s a simple word. But why the heck isn’t it curiousity? I guess the key is that you drop the “u” sound when going from “curious” to “curiosity,” but it still messes with me. Ubiquitous just has way too many vowels. Silhouette is French, and I always screw up French words. There’s no reason for there to be an h in it, nor a u, really. And the problem with schizophrenia is that it’s prounounced “skit-za-phrenia,” so you expect a t in there, and you don’t expect it to start sch. But it does.
