The term cartoon has more than one meaning.
A cartoon is a humorous illustration or other drawing. It is related to caricature, but usually does not parodize a real-life person such as a politician. Instead, cartoons typically feature fictitious characters.
A cartoon is not a comic, although a great number of comic artists draw their comic characters in cartoon style. The difference is that a comic is sequential art; it narrates a story using a sequence of picture panels, while a cartoon is only a single drawing.
Typical features of a cartoon are exaggerated figure proportions, poses, gestures and mimics. Also, most cartoons are drawn with greatest possible abstraction from unneccessary detail and (photo)realism. Figures and objects are typically drawn in black outlines. Pleasant, smooth, rounded shapes prevail in the line art. The areas enclosed by the outlines can be colorized or left white.
The term cartoon can also refer to animated movies; see "animation".
