Difference between Interfere and Intervene

The English verbs interfere and intervene are closely related, both sharing the prefix "inter-" (meaning "between"), yet they differ significantly in their connotations and typical usage. Understanding the distinction between these terms will help you choose the most appropriate word in different contexts, particularly in British English.

Interfere

Interfere means to become involved in a situation where your involvement is unwelcome or unnecessary, often causing disruption or hindrance. The word is almost always used negatively, implying that someone is getting in the way or obstructing a process or another person's affairs.

For example:

  • "Don’t interfere in my personal life. It’s none of your business."

  • "Please don’t interfere when I’m working."

  • "The rough desert floor interferes with the flow of air over it."

In these sentences, interfere suggests that the action is unwanted and likely to cause annoyance or problems for others. If you say someone is "interfering," you are usually criticising them for meddling where they are not needed or wanted.

Intervene

Intervene, on the other hand, means to intentionally become involved in a difficult situation, usually with the aim of improving it, preventing harm, or resolving a conflict. The connotation of intervene is generally neutral or positive, as it often implies helpful or necessary action.

For example:

  • "The referee had to intervene to stop the fight between the players."

  • "The government asked the district collector to intervene in the issue and solve it immediately."

  • "There is increasing demand for the United Nations to intervene in trouble spots throughout the world."

In these examples, intervene describes stepping in to help, mediate, or prevent something negative from happening. It is often used in formal or official contexts, and the action is usually seen as justified or beneficial.
