R5804 TIL that I've been calling everything an ACRONYM when in fact they could instead be an INITIALISM. An acronym can be spoken like a word e.g. FIFA, NASA, RAM, where as an initialism cannot be easily spoken as a word e.g. FBI, CIA, UFO, HSBC, and are instead pronounced letter by letter.
X01KE TIL that an acronym that cannot be pronounced as a word is not an acronym, it's an initialism. NASA and FIFA are acronyms but USA and FBI are initialisms!
