Use interfere in when someone becomes involved in a situation, especially when that involvement is unwanted.
- Don’t interfere in their personal affairs.

Interfere vs. Meddle
Interfere is broader than meddle.
- Interfere can describe unwanted involvement or disruption.
- Meddle usually describes unnecessary involvement in other people’s affairs.
Compare:

Here, meddle would not work.

Here, meddle clearly emphasizes unwanted involvement.
Interfere vs. Intervene

Intervene often suggests taking action to help, control, or resolve a problem.
Interfere often suggests unwanted or unnecessary involvement.
- The doctor intervened to help the patient.
- His brother interfered in their argument.
Therefore, intervene can be neutral or positive, while interfere often carries a negative sense.

Interfere has a broader meaning and can involve affecting or preventing something from working properly.

Interfere vs. Obstruct
Obstruct focuses on blocking progress or movement.
Interfere can mean affecting something without completely blocking it.

Both words can describe making progress more difficult.
However, hinder usually focuses on slowing or making progress harder, while interfere is broader.
