Fast
Abstaining from meals
Fast means moving or able to move quickly: a fast car, a fast runner.
It extends to anything happening in a short time: fast food, a fast learner.
A clock running fast shows a time later than actual.
Fast can mean firmly fixed or loyal: fast friends, hold fast.
Colors that are fast won't fade.
To fast is to abstain from food, usually for religious or medical reasons—a completely separate word that happens to share the spelling.
