Peppery describes a sharp, spicy taste or smell like black pepper, or a personality that's irritable and short-tempered.

When you bite into something peppery, you feel that distinctive tingle and heat on your tongue. Arugula has a peppery flavor that makes salads more interesting. Ginger snaps taste sweet but also peppery from the spices. A bowl of chili might have a peppery aroma that makes your nose tingle before you even take a bite.

The word also describes someone with a hot temper who gets annoyed easily. A peppery coach might snap at players who aren't paying attention. Your grandfather might get peppery when neighborhood kids cut through his garden.

You might notice that peppery people often aren't truly mean. They just react quickly and sharply when frustrated, like how pepper hits your taste buds fast and strong. The sharpness passes, but you definitely notice it while it's there.
