Beyond the definition

Suppression isn't just about keeping something down—it's about actively putting pressure on it to prevent it from happening or being expressed. Think of a garden where weeds are constantly popping up. You can ignore them, but suppression means you deliberately pull them out before they take root.

Historically, "suppression" comes from the Latin word meaning "to press down." This idea of forceful restraint is key. A government might suppress dissent (opinions that disagree with it), a doctor might prescribe medication to suppress a cough, or someone might suppress their anger to avoid an argument. It's not just having feelings; it's actively working to keep them hidden or controlled. Sometimes suppression can be harmful—like when people suppress their emotions for too long.
