✅ Abbreviation
An abbreviation is a shortened form of a word or phrase. It can include:
- Initial letters (e.g., USA for United States of America)
- Parts of words (e.g., approx. for approximately)
- A combination of letters and numbers (e.g., B2B for business-to-business)
📌 Key Point: Not all abbreviations are acronyms.
✅ Acronym
An acronym is a type of abbreviation—but it’s made from the initial letters of words, and it’s usually pronounced as a word.
Examples of acronyms:
- NASA = National Aeronautics and Space Administration
- SCUBA = Self-Contained Underwater Breathing Apparatus
- RADAR = Radio Detection and Ranging
📌 Key Point: Acronyms are abbreviations you can say like a word.
