Answer:
the use of symbols in cartoons is commonly known as symbolism. the illustrator uses symbol to get a certain point across
these points can come in different categories:
Exaggeration
Sometimes cartoonists overdo, or exaggerate, the physical characteristics of people or things in order to make a point.
When you study a cartoon, look for any characteristics that seem overdone or overblown. (Facial characteristics and clothing are some of the most commonly exaggerated characteristics.) Then, try to decide what point the cartoonist was trying to make through exaggeration.
Labeling
Cartoonists often label objects or people to make it clear exactly what they stand for.
Watch out for the different labels that appear in a cartoon, and ask yourself why the cartoonist chose to label that particular person or object. Does the label make the meaning of the object more clear?
Analogy
An analogy is a comparison between two unlike things that share some characteristics. By comparing a complex issue or situation with a more familiar one, cartoonists can help their readers see it in a different light.
After you’ve studied a cartoon for a while, try to decide what the cartoon’s main analogy is. What two situations does the cartoon compare? Once you understand the main analogy, decide if this comparison makes the cartoonist’s point more clear to you.
Irony
Irony is the difference between the ways things are and the way things should be, or the way things are expected to be. Cartoonists often use irony to express their opinion on an issue.
