Crayon is a stick of colored wax, charcoal, chalk, or other material used for drawing or coloring.
The word "crayon" comes from the French word "craie" (chalk) and the Latin word "creta" (earth).
Common types of crayons include:
1. Wax crayons - the most common type used by children
2. Oil pastels - softer and more vibrant than wax crayons
3. Watercolor crayons - can be used dry or with water
