Acronym vs. Initialism

What's the difference between an acronym and an initialism?

The difference between an acronym and an initialism is how they are pronounced and formed.

Acronym: An acronym is formed from the initial letters of a phrase or series of words and is pronounced as a word. For example, "NASA" (National Aeronautics and Space Administration) and "LASER" (light amplification by stimulated emission of radiation) are acronyms.

Initialism: An initialism is formed from the initial letters of a phrase or series of words, but each letter is pronounced individually rather than as a single word. Examples include "FBI" (Federal Bureau of Investigation) and "BBC" (British Broadcasting Corporation).
