leak

A leak isn't always water dripping from a pipe. It can also mean private information getting out, like a news leak before an official announcement. It also describes an unwanted opening that lets something pass through, whether it's air from a tire, gas from a pipe, or water from a roof. Think of a ship with a hull leak; water gets in where it shouldn't. In the same way, a politician might try to "plug a leak" in a campaign after damaging information is revealed.

Imagine a carefully constructed dam holding back a vast lake. If there's a tiny crack, a leak begins—a slow, insidious escape of water. That's the core idea behind this word: an unintended passage or release. A leak can be physical, like water seeping through a roof, or figurative, like confidential information being revealed to the public.

You might hear about a "media leak" when sensitive documents are shared with journalists before they're officially released. This suggests someone deliberately (or accidentally) allowed private information to escape. A detective might try to find the leak in an investigation—the person who is sharing details with the suspect.

But it's not always about secrets! A leak can simply describe a flaw or opening. "There was a gas leak in the kitchen" means gas escaped from a faulty pipe. In a sports context, a team might be described as having a "leaky defense" if they allow the opponent to score too easily. Historically, the word traces back to Old Norse and Middle Dutch roots meaning "to drip" or "allow water through," suggesting something flowing out of its intended path. Today, it's used across countless contexts: plumbing, politics, sports, and beyond. So, if something is escaping where it shouldn't, you're likely dealing with a leak.
