Word that I learned today: "Caveat" Definition: "Caveat" is a noun that means a warning, caution, or condition that should be considered before proceeding with something. It often indicates a limitation or exception. Ex. sentences: 1. You can borrow my car, but with one caveat—you must fill up the gas tank before returning it. 2. The study is promising, but there are some caveats regarding the small sample size.
