Acronyms = Pronounced as new words
Initialisms = Each letter is said separately
Acronyms and initialisms are both forms of abbreviations (shortened forms of words or phrases).
Pro tip: In everyday conversation, people often say "acronym" for both — but now you know the technical difference!
Speak each letter separately.
Note: All of the abbreviations listed above are initialisms, though ASAP and SaaS can also be used as acronyms (say “AY-sap” and “sass”).
You can use these in correspondence with colleagues in a less formal tone.
Speak each letter separately.
✅ Know your audience — not everyone knows every abbreviation
✅ When in doubt, write it out
