Other forms: illustrators
An illustrator is an artist who draws the pictures in a book. Some children's book authors are also illustrators, while others work with an illustrator.
Picture books have to be well-written and well-illustrated: it's up to an illustrator to interpret the story through pictures (or illustrations). Illustrators sometimes also draw or paint pictures for comic books, advertisements, magazines, greeting cards, and graphic novels. In the 16th century, an illustrator was "one who enlightens," from a now-obsolete meaning of illustrate, "light up." The Latin root is illustrare, "light up," and also "adorn."
