Pet peeve --
Misuse of the word "acronym." If you do not pronounce the letters as a WORD, is is NOT AN ACRONYM!
Examples of things that are NOT acronmys --
FBI, CIA, DEA, SEC, etc. Those are initialisms, but not acronyms.
Examples of acronmys (Each letter stands for something, but these are all pronounced as a WORD instead of saying the actual letters) -- NATO, OPEC, AIDS, ADIDAS, SCUBA, etc.
Note that the acronyms are also initialisms. All acronyms are initialisms, but not all initialisms are acronyms.
The word "abbreviation" is best use for shortening a word or series of words, such as "min." "max." and "Dept. of Ed."
