Slang and Jargon: What are they?

Jargon is used in Medicine.

When we think in a group of words used by a single community of people we tend to think on Slang. However, we have to know how to establish differences between slang and jargon or specialist language. The main difference is their formality and usage. 


Jargon can be easily defined as a group of words from a determined group of people, usually related to their work (Medicine, construction, cooking, etc). This words are formal and have meanings known by all the people of a group, and are needed to develop their work.


In the other hand, Slang is also a group of words from a group of persons, but it's informal and it's more related to social differences (Age, social class, location, etc). Slang may be used by gangs or thieves to hide their communication, or in chats to write words shorter and faster.
