Other forms: dancers
A dancer is a person who performs by moving their body to music. A ballet dancer, a professional dancer, a good dancer.
The professional kind trains from childhood and has one of the shortest careers of any performing art — most classical dancers retire in their thirties, which is why teaching and choreography follow. The word covers the amateur just as well. Note dance, dancing; and that dance came into English from French and displaced the older English word.
