Difference Between Jargon, Slang, and Colloquialism
There are similarities between the definitions of jargon, slang, and colloquialism, as they are all terms referring to specified language only used by certain groups. Colloquialisms are specific terms and phrases that are informal and often idiomatic. Colloquialisms are often bounded by a geographical region, like the variation in the United States of where the words "soda," "pop," "soft drink," and "Coke" are used. Colloquialisms are not bounded by age or class. Slang, while also being informal language, is generally used in social groups such as by teenagers. Thus, slang is bounded by geography, age, and class as well.
Jargon, on the other hand, can be understood by anyone who is part of an industry, and thus the individual often makes a choice of whether or not he or she is a part of that group. Jargon is limited not by region, class, or age, but instead by the choices that a person makes to join a sport, participate in a certain art form, or take on a certain career.
