The tongue is a muscular organ in the mouth that is used for tasting, speaking, and swallowing. It is made up of eight muscles that allow it to move in all directions. The average tongue is about 3 inches long, but some people have tongues that are longer or shorter.
There is no known way to make your tongue longer, but there are some exercises that can help to strengthen the muscles in your tongue and improve its range of motion. These exercises can be helpful for people who have difficulty speaking or swallowing.
