Absention refers to being absent or staying away from a particular place or event. Its antonyms are presence, attendance, and participation. Presence refers to being there physically, mentally or emotionally. Attendance refers to being present in a formal or official capacity, such as at school or work. Participation refers to actively engaging or taking part in an event or activity. The opposite of absention is all about being there, showing up, and being involved. These antonyms play a crucial role in communication, for instance, if someone is expected to be present in a meeting, and they are not, their absence can lead to confusion or delay in decision making.
