Passively means accepting or allowing something to happen without taking action, resisting, or getting involved. When you watch passively, you observe without participating. When you accept something passively, you let it happen without pushing back or trying to change it.

Picture a classroom where one student makes fun of another. A student who responds passively just sits there, neither defending the target nor speaking up. They're not actively joining the teasing, but they're not doing anything to stop it either. In contrast, an active response would mean stepping in, telling the bully to stop, or getting help from a teacher.

The word often describes a kind of mental or physical inaction. Someone watching TV passively just stares at the screen without thinking critically about what they're seeing. A student who learns passively copies notes without asking questions or making connections. Scientists might observe animals in nature passively, watching without interfering or changing their behavior.

Passive (the adjective form) suggests letting things happen to you rather than making things happen.
