Intervention means getting involved in a situation to try and make it better or to prevent it from getting worse. It can be done by someone who is not directly involved in the situation but wants to help in some way. For example, a doctor might intervene to save someone's life, or a teacher might intervene to help a student who is struggling. It can also refer to a program or service designed to help people in need, such as an intervention for drug addiction.

When to use it

Intervention is often used to describe a situation where someone is intervening or stepping in to help another person who is struggling with a problem. It can also refer to a formal procedure that is used to help someone overcome an addiction or other disorder.

For example, if a friend is suffering from alcoholism and is unable to quit drinking on their own, an intervention may be staged where friends and family members gather to confront the person and urge them to seek professional help. Similarly, if a student is struggling with a specific subject in school, a teacher may intervene by offering additional resources and support to help the student understand the material.

In a medical context, intervention may refer to a procedure or treatment that is used to treat a patient's illness or condition. For example, a doctor may perform a surgical intervention to remove a tumor or recommend a medication intervention to treat a chronic disease.
