Homonym: trigger (Event)
A "trigger" refers to a stimulus that causes a reaction or response. In psychology, it often relates to a specific event, situation, or memory that provokes strong emotional reactions, such as anxiety or anger. Triggers can vary widely from person to person, depending on their experiences and sensitivities.
In everyday language, a trigger can also mean anything that initiates a process or action. For example, pulling the trigger on a gun activates the firing mechanism.
