“Jargon is a type of language that is used in a particular context and may not be well understood outside of it.
The context is usually a particular occupation (that is, a certain trade, profession, or academic field), but any ingroup can have jargon.”
The key part of this definition is “may not be well understood outside it.”
A writer, when using a term, should ask “is my audience likely to understand this word?”
If the answer is yes, then proceed with it.
If the answer is anything less than a yes (maybe, maybe not, no), then the writer should eliminate all misunderstandings by defining the term.
Not til what we write is devoid of jargon can we expect all others to understand what we are talking about.
For example, the term “Global Value Chains” might be jargon to a non-economist audience.
The writer could define it, in brackets, such as:
Global Value Chains (that is, cross-national production networks) arose when advancements in communication technologies (such as telephone and email) dramatically reduced the costs of co-ordination over long distances, meaning firm owners could organize production processes without being physically present, and could, for example, give instructions while in another country.
