Descriptive means giving details about what something is like, rather than judging whether it's good or bad. When you write a descriptive paragraph about your bedroom, you explain what someone would see, hear, or smell there: the blue walls, the squeaky wooden floor, the smell of your dog's blanket in the corner. You're painting a picture with words.

In grammar class, descriptive writing uses specific details and sensory language. Instead of writing “the cake was good,” a descriptive sentence might say “the chocolate cake had thick, glossy frosting and smelled like vanilla.” The second version helps readers imagine exactly what you experienced.

The word contrasts with prescriptive, which means telling people what they should do. A descriptive grammar book explains how people actually use language: “Many people say 'different than' in casual conversation.” A prescriptive grammar book gives rules: “You must say 'different from.'” Scientists aim for descriptive research, observing and recording what happens without inserting opinions about whether it's right or wrong.

When you're being descriptive, you're like a reporter or photographer, capturing the details of what you observe so others can understand or picture it clearly.
