Hi - is there a definitive answer as to whether there should be an apostrophe after, for example, CDs, where the abbreviation is for compact discs in the plural? To my mind, there shouldn't be, although 'the CD's jewel cases', being possessive, should have one.
I ask only because someone very pedantic insisted there should be one in my first example. I've looked in Fowlers, but my copy is pretty old and things may have changed.
It's not of earth-shattering importance, but it's niggling me!
I also agree with you so I recommend you be pedantic back and stop the niggling;-)
Of course it is not just the "apostrophe" which causes problems. For example should you be Exdragon or Ex-dragon? When one of my previous employers changed its name from Cuckfield And Crawley Health Authority to Mid-Downs Health Authority you would have no idea how much time and money was spent in trying to figure out if it should have a hyphen or not. Clearly the hyphen argument won and we had to pay a fraction more to the livery artists who were respraying our whole transport fleet.
I would go for CDs ... slightly off subject; yesterday, I used about 50 redundant plastic CD jewel cases to form a 4" raised border along the brickwork that surrounds my well-kept lawn....clear...black, clear...black, clear...black... it looks quite neat, I knew they would come in handy...for something.
