If you like “hundred dollar words,” then perspicacious definitely fits that category.   I have a better than average working vocabulary, but I have to admit I had to look this one up to learn its definition.

When my therapist used it in our session this week (referring to me!), I felt like a big dummy because I had no idea what it meant.  I asked him for a pen so I could write the word down to remind myself to use it as this week’s featured word.   I was surprised that I actually spelled it correctly.   It’s a good word to use in conversation if you want to sound either really pretentious or really smart perspicacious.
