While there are terms like:
* "Unpronounceable" - This simply means the acronym cannot be spoken as a word.
* "Initialisms" - These are acronyms that are pronounced by saying each letter individually (e.g., FBI, CIA).
However, there is no widely recognized term for an acronym that is specifically designed to be unpronounceable, as this isn't a common goal when creating acronyms.
If you need a term, you could use phrases like:
* "Unpronounceable acronym"
* "Acronym with no spoken pronunciation"
* "Acronym meant to be read as letters"
It's important to remember that even if an acronym is considered unpronounceable, people might still try to pronounce it in a way that makes sense to them.
