Some students familiar with English gain their abilities through the workplace, bringing a wide range of vocabulary to the classroom. These words can be specialized to the point of being unusable, and corrections should be made to allow the student to accurately communicate with people outside of their industry.
About 12 years ago, we had a doctor who specialized in endoscopic medicine, and performed biopsies on cancerous tissue on a weekly basis. He was dismayed that when talking to native English speakers, he was unable to be understood. This was corrected by moving away from the Latin and Greek that his words were based off of, and converting them into English.
For the sake of clarity, endoscopic became “inside looking”, and biopsy became “living medical examination or inspection”. Many more people began to understand what he was talking about, and therefore held a higher opinion of him.
