What is meant by 'jargon' in communication?

Jargon refers to the specialized language or terminology used by a specific profession, group, or community that is not easily understood by outsiders. This language often includes technical terms and phrases that are unique to that particular field, allowing members of the group to communicate complex ideas succinctly and effectively among themselves.

For instance, in medicine, terms like "myocardial infarction" may be used instead of "heart attack," which can streamline communication among healthcare professionals but could confuse individuals without a medical background. Therefore, jargon serves as a shorthand for those who share a common understanding of the subject matter, enhancing clarity among the informed while potentially alienating those who lack that specialized knowledge.
