A leak is an opening or crack that allows fluid to escape from a container. You might have a leaky faucet at home.
When talking about a leak, people usually mention the problem of something getting out, like water from a pipe or air from a tire. Imagine you're trying to fix a dripping faucet and you find it's because there's a tiny hole somewhere in the pipes. That's a leak! You might also hear someone say they've got a leak in their wallet – that means money is being spent quickly and maybe even unexpectedly.
A crack, crevice, fissure, or hole which admits water or other fluid, or lets it escape.
Example: a leak in a boat
To allow fluid or gas to pass through an opening that should be sealed.
Example: The faucet has been leaking since last month.
