70+ Big Words That Will Make You Feel Smart

The biggest word in the English language is 189,819 letters long, and takes three hours to pronounce! More commonly used big words are several syllables long, and often make people feel smart when they say them out loud. Somewhat ironically, however, study after study has shown that using big words usually makes people sound dumb.

Mark Twain has a couple good quotes about why writers should be economical and precise:

“Don’t use a five-dollar word when a fifty-cent word will do.”

“The difference between the almost right word and the right word is really a large matter – it’s the difference between the lightning bug and the lightning.”

Still, it’s kind of fun to learn that a big juicy ass can be described as “callipygian” and if you’re horny as hell but don’t want anyone to know, just say you’re feeling “concupiscent.”
