Horn
From Wikipedia, a free encyclopedia written in simple English for easy reading.
Horn means several things. Two of the most common uses are an animal's horn or a horn on a car.
Animals that have horns have projections (things that stick out) made of hard skin. The horn has a lot of keratin in it, the same protein that is in your hair and nails.
A car horn is most often found in the steering column in a car. When pressed, it makes a loud noise that other drivers can hear. It is for alerting them to possible dangers.
