Think of these capitalized letters as MUST-KNOW vocabulary.

What is an initialism?

Some people feel strongly that the term acronym should only be used for terms like NASA, which is pronounced as a single word, and that initialism should be used if we say the individual letters in an abbreviation such as FBI.

Research shows that acronym is commonly used, at least in the U.S., to refer to both types of abbreviations. However, since this is an English blog, we’ll go ahead and call them what the correct term is: initialisms.

In the list below you will see 67 Very Common Initialisms in Spoken American English. That’s right, we say these, we spell them out. We use the initialism on the left MORE FREQUENTLY than what the term stands for. I repeat, read the initialism; one letter after the next.
