It's like a strong, soft muscle that can move around inside your mouth that helps you chew and swallow. It has little bumps on it called taste buds that help you sense different flavors. It can also move into different positions in your mouth to help you form sounds when you speak.

Examples:

1. I can taste with my tongue.
2. The dog wagged its tail and stuck its tongue out.
3. The ice cream was so cold, it made my tongue numb.
