Sometimes, however, a word has a very specific meaning and is still used incorrectly. If you've seen the movie The Princess Bride you may remember the scene in which the Wallace Shawn character is told that he is being followed. He responds more than once saying, "inconceivable!" Finally one of his henchmen says, "I don't think you know what that word means, boss."
Even if one feels compelled to use jargon, most jargon terms have specific meanings.
I once had a manager nearly twenty years ago who picked up jargon like a chameleon adapts to its surroundings. We worked with a lot of engineers based in India and he picked up their the phrase, "at the earliest." That is a highly non-grammatical construct used by engineers whose first language is not English. It means, as you might surmise, "as soon as possible." Once in my performance review this manager used the phrase "just in time" regarding my providing feedback to an employee. That phrase has to do with the manufacturing process and getting parts to the factory right before assembly, and not any earlier, to save on inventory costs.
That’s obviously not what he meant. He meant I should provide feedback to this employee promptly, and simply stating "prompt feedback" would have made a lot more sense.
A little thought can frequently eliminate such simple errors.
