Can VM be written in vowelless Latin?

If you recognize that your key is ambiguous, just change it; after all it was you who determined it.

It doesn't work that way. The key may be changed only if it's incorrect, not if it's ambiguous.

I couldn't find a dictionary that would translate the word partus as part. I use Gaffiot or Olivetti (also available in English) which gives the list of existing Latin words, which is very advantageous for a beginner like me.

I'm very frivolous with noun endings, especially with 3rd declension nouns
