But did you know that there are other types of abbreviations? It's true. There are acronyms and initialisms. The difference between the two is really simple.
Acronym - this is an abbreviation pronounced like a word formed from the first letter of a series of words. Articles are usually dropped. Sometimes more than the initial letters are used to form the new word.
Examples:
NASA - National Aeronautics and Space Administration
AIDS - Acquired Immunodeficiency Syndrome
Some businesses have initial-letter upper-case, and everything else lower-case.
Examples:
Alcan - Aluminum Company of Canada
Nortel - Northern Telecom Ltd.
Initialism - this is an abbreviation that is not pronounced like a word formed from the first letter . Each letter is said individually. The letters are always upper-case.
Examples:
CBC - Canadian Broadcasting Corporation
RCMP - Royal Mounted Canadian Police
FBI - Federal Bureau of Investigation
OMG - Oh my God
