pee

The word "pee" is an informal word for urination, the act of letting urine leave the body. It can also mean the urine itself. People use it all the time in everyday speech, especially with children, family, or close friends. Humans and animals both pee as a normal body function.

The word began as a softer way to say a rougher word, and over time it became a normal, widely accepted choice. It is still informal, but it usually sounds mild rather than rude. You might hear a parent ask, "Do you need to pee before we leave?" or a child say, "I peed in my pants!"

Beyond the act itself, "pee" also refers to the liquid waste. In a medical setting, someone might still casually say "pee sample," though "urine sample" is more formal. In writing, schoolwork, or professional contexts, "urine" and "urinate" are often better choices. In daily life, though, "pee" is one of the most common and easy-to-understand words for this basic body need.
