It is standard advice for any kind of writer to avoid jargon. It’s ugly, it excludes, it baffles as much as it communicates. And yet, people love it.
When training people in writing, I have had few delegates protest when I have suggested they remove the more nonsensical examples of jargon, particularly business jargon, from their work. I’m thinking of the ill-defined claims of so many companies that they offer “solutions”, or that they are “leveraging” something or other, possibly a “vertical”. I would advise my trainees to be concrete, be specific, and most people would go along with it.
It is not, though, as simple as all that. We hate jargon, except when we are using it ourselves, and then we find it indispensable as a shorthand and a way making ourselves feel part of a team. In that case we would be using our professional or specialist language – and we would be right to use it. No-one expects brain surgeons to use the same work vocabulary as nuclear physicists.
Jargon really means specialist language we dislike; it’s a pejorative term rather than a descriptive one. Originally the word meant the twittering and tweeting of birds. Human beings didn’t understand it, and they didn’t like it: it is easy to see how this transferred to the incomprehensible jabberings of other people. Foreign languages were often referred to as jargon, although they are not, of course. They are perfectly clear to those who speak and understand them.
The key thing, really, is to be aware of your audience. That is always the first principle in writing – who is this for? – and it starts with the language you use. By all means use the technical terms of your business or profession when you are writing for readers within the same world: but if you are writing for outsiders, you need to think about how they will receive it. Will they be baffled? Will they feel excluded? Will they dismiss what you have to say because of the thoughtless way you have chosen to express it?
So I would say this: when you are writing for your customers or the general reader, take out the jargon, except where you are sure they will understand and accept it. Be particularly rigorous about buzzwords and management clichés, which provoke a cynical response.
That said, not everything can be expressed in standard English. Other people’s technical terms and occupational slang can be pungent and authentic, and we love them when we encounter them in fiction or drama. Would The Wire, often acclaimed as the best-ever television drama series, have been the same without its relentless use of US Police jargon?
