Lint is a term used to describe small pieces of fabric, thread, or other material that accumulates on clothing and other surfaces. FUR is a three-letter word that refers to the soft, thick coat of an animal such as a bear or rabbit. FUZZ is a four-letter word that is similar to FUR but is usually shorter and less dense. FLUFF is a five-letter word that is similar to FUZZ but is even softer and lighter. All three words can be used to describe lint.
