What is a swatch

When I first got into quilting and started buying fabric online, the word swatch would appear. I guess that it was a sample of fabric for a discounted price. I haven't found any free swatches, but Amazon.com lets you buy some. Here is the link for the definition of a swatch - https://www.merriam-webster.com/dictionary/swatch
