FYI: ICYMI Is An Initialism; Snafu Is An Acronym; They’re Both Abbreviations
If an abbreviation formed from the first letters of several words is pronounced as one word, it’s an acronym. Gif, laser and snafu are examples.
If such an abbreviation is known by its letters, it’s an initialism. Think ATM, BBC and FBI.
“Email” is an abbreviation. It’s also what we will get if we call an initialism an acronym or an acronym an initialism.
