interfere

Imagine building an elaborate sandcastle on the beach. If someone comes along and starts kicking it down or rearranging your carefully crafted towers, they are interfering! To interfere means to get in the way of something, often causing disruption or preventing it from happening as planned.

It can be a deliberate act, like a politician interfering in an election, or an unplanned one, like making a friend's day harder by stepping in at the wrong time. We usually use the word for unwanted involvement that changes what would have happened naturally. You might ask someone not to interfere in an argument you're having with a sibling because you want to work it out on your own.

To interfere means to get involved in a situation or process in a way that hinders or disrupts its progress. It implies an intrusion into affairs that don't directly concern you and often carries a negative connotation of unwanted involvement.

The word is commonly used in two main patterns: interfere in and interfere with. Interfere in is often used for getting involved in matters, decisions, or conflicts that are not really yours. Interfere with is often used for blocking, disturbing, or affecting an action, process, or object. For example, "The government decided not to interfere with the free market" means they chose to let economic forces run their course without stepping in. "I tried not to interfere in my daughter's decision" shows restraint by letting her choose for herself.

Interference can also describe physical or technical obstructions. You might say, "The heavy storm interfered with the radio signal," meaning the weather disrupted the clear transmission.

While the word is usually negative, it can sometimes describe a necessary disruption. In medicine, for example, a doctor might interfere with the natural progress of a disease to save a patient. Still, when the action is helpful or welcome, English more often uses the word "intervene." In the end, interfere suggests crossing a boundary and changing the course of something in a way that is often unwanted.
