Sensitive describes someone who feels things deeply or responds strongly to what's happening around them. A sensitive person might cry during a sad movie, feel hurt by a casual joke, or notice when a friend seems upset even when no one else does. Their emotions are close to the surface, like a smoke alarm that detects even a small amount of smoke.

Being sensitive can be a strength. Sensitive people often make caring friends because they pick up on feelings others miss. They might notice when someone needs help or encouragement. Artists, writers, and musicians are often sensitive because they feel emotions intensely and can express them in their work.

The word also describes things that react easily to changes. Sensitive skin might turn red from certain soaps. A sensitive topic is one that makes people uncomfortable or upset, like bringing up someone's recent mistake. Scientific instruments can be sensitive too: a sensitive thermometer detects tiny temperature changes that ordinary thermometers miss.

Sometimes people use sensitive to mean easily offended or overly emotional, but that's not always fair. What looks like overreacting might just mean someone experiences the world more intensely than others do. The key is learning to manage strong feelings without letting them control your reactions or relationships.
