Sample means a small part of something that shows what the whole thing is like. When you try a sample of ice cream at the store, that single spoonful helps you decide if you want a whole scoop. When a scientist takes a sample of pond water, she examines those few drops to understand what's in the entire pond.

The word works as both a noun and a verb. A doctor might collect a sample of your blood (noun) or test it in the lab (verb) to check for signs of illness. A musician might sample a few seconds from an old song, using that snippet as part of a new recording.

Samples give us information without having to examine everything. A quality control inspector doesn't taste every cookie coming off the factory line; she samples a few from each batch. Political pollsters don't ask every voter who they support; they sample a few thousand people to predict how millions will vote. Market researchers offer free samples of new products to see how customers react.

The key idea is that a good sample truly represents the larger whole. If you want to know whether a recipe works, you sample the dish while cooking. That small taste tells you if the whole pot needs more salt.
