Jargon is specialized language used among members of a trade, profession, or group. Use jargon only when readers will be familiar with it; even then, use it only when plain English will not do as well.
Jargon offers efficiency and specificity to people within the group, but it excludes those outside the group.
Broadly defined, jargon includes puffed-up language designed more to impress readers than to inform them.
Sentences filled with jargon are hard to read, and they are often wordy as well.
