@[email protected] is right.
An acronym is a word formed from the initial letters of other words and pronounced as a single word.
An abbreviation is a shortened version of a word or phrase used to save time and space, avoid repetition, or follow convention.
All acronyms are abbreviations, but not all abbreviations are acronyms.
SMH and ATM are both abbreviations. NASA, radar, laser etc. are all acronyms.
Ok, but you’re still technically (and factually) wrong.
