halt

A halt is when you stop moving or doing something suddenly.

You use "halt" quite often in your daily life. For example, if you're driving and someone stops their car right in front of yours, that's a halt. You might also say "Let's put the construction project on hold until further notice" which means it's halted temporarily. Some sports teams will call a halt to the game if there's an injury or severe weather. A doctor might tell you to stop taking a certain medication due to side effects, and that would be another example of a halt.
