Composure means being calm and collected, especially in a difficult or stressful situation. It's about keeping your cool when things get tough.
When someone says "She showed great composure under pressure," they usually mean that she stayed calm and didn't let her emotions get the best of her. This can happen in many situations, like during a big presentation at work or while watching a sports game. Sometimes people might even talk about having lost their composure, which means they got really upset or flustered. In everyday life, maintaining your composure is often considered an important quality because it helps you think clearly and make better decisions when things are chaotic.
Calmness of mind or temperament.
