I always use English abbreviations. They help me save time and space in writing (but also in speaking), and I use them in formal and informal contexts.
But I didn’t know there were 2 types of abbreviations! Initialisms and acronyms. What’s the difference?
Let’s get technical for a few seconds…
- Initialisms: these are abbreviations where each letter represents a word and you pronounce each letter individually (e.g. BBC)
- Acronyms: they’re the same as initialisms, but you pronounce all the letters as a single word (e.g. NASA)
End of the lesson 🙂 It’s now time to see some of these little guys in context.
In this post, I’ll show you the most common English abbreviations (initialisms + acronyms) so you can integrate them naturally into spoken and written conversations.
We’ll look at:
