(I don't know if this is the right place to ask this; if it's not please let me know.)
I want to name something with an acronym, and I found a very good word for it, but there is a word (in the meaning of the acronym) that starts with "n" and in my acronym the corresponding letter is "u". My idea is that the "u" is an "n" upside down (lowercase). I would like to use an acronym that is easy to pronounce and remember.
It would be complicated to describe my actual acronym, but as an example: let us suppose the meaning is "chocolate, oats and milk" (I am not feeling very creative at the moment) and I want to use the acronym "Cow" instead of "Com", using a "w" as if it was an "m" upside down.
My questions are:
1) Is this acceptable?
2) Are there other examples of "inexact" acronyms like mine?
3) Does this practice have a name?
