Acronyms

Acronyms are like initializations except that the initials are said as a word instead of as a series of letters.

First, here are some initializations: 


	FBI: Federal Bureau of Investication

	UFO: unidentified flying object

	BLM: Bureau of Land Management
Here are some acronyms: 

	NATO: North Atlantic Treaty Organization

	SWAT: Special Weapons Action Team

	SNAFU: situation normal, all fouled up

	PIN: Personal Identification Number

	SCUBA:  Self-Contained Underwater Breathing Apparatus

	AIDS: Acquired Immune Deficiency Syndrome

	NASA: National Aeronatics and Space Administration
Acronyms are more or less the same sort of thing. The difference is that with initializations the letters are said separately and with acronyms the letters are said as a word.
