When I first started here years ago, I read the glossary. Many in the glossary are not used, and many more often used are not in the glossary. In other words not much help.

Many seem to use them to convince us how clever they are. And then there are probably others who like the challenge of figuring them out.

I remember encountering a medical abbreviation on the chart. No one could figure it out so the professor circled it and wrote - first prize.
