We use a lot of abbreviations for common (and uncommon ) words everyday. Some examples would be saying "app" instead of application; "info" instead of information, and so on. We also use many initial abbreviations, and never think about what the initials actually stand for. We have been discussing the dumbing down of Americans, and losing our abilities to read and write cursive as the generations pass. As I was writing a post here, and adding a PS on the bottom; I stopped to think how we all use this abbreviation for the words "post script", and I wondered how many of the younger folks have grown up using the initials, and have no idea what they stand for, or what it even signifies if they do know the actual words. Some other ones would be BC>before Christ (now used as BCE >before common era) and AD>Anno Domini (year of our Lord); AM and PM> ante meridian, post meridian; etc> et cetera, just to name a few. What other ones are there ?
