From what I know an abbreviation is just a shortening of a word, such as Dr. (Doctor) or Mr. (Mister), whereas an acronym is a specific type of abbreviation where the first letters of multiple words are put together to make a single word describing the original phrase, such as NASA (National Aeronautics and Space Administration).

The word 'abbreviations' and 'acronyms' are often used interchangeably. Abbreviation is a version of a word or phrase that has been reduced in length used to represent the whole word. Example: For North Americans, math is the preferred abbreviation for the word 'mathematics' . For the UK, maths is the preferred abbreviation for word 'mathematics' . Acronyms is a type abbreviation that are pronounced as words. We do not say each letter at a time. Examples: Teaching English to Speak of Other Languages - TESOL Acquired Immune Deficiency Syndrome - AIDS radio detecting and ranging - Radar self-contained underwater breathing apparatus - Scuba You live only once - YOLO Initialisms, uses the first letter of every word of the phrase, is a type of abbreviation that are pronounced one letter at a time. Examples: Federal Bureau of Investigation - FBI (Each letter pronounced separately) By The way - BTW (Each letter pronounced) Sometimes Initialisms are also acronyms. Example: As soon as possible - ASAP (can be pronounced as one word or one letter at a time). I hope this clarifies the differences.

For example, Auto pilot uses auto as an abbreviation for automatic. Legit is an abbreviation for legitimate
