 I apologize, but my point remains 

Hi. I apologize for calling you rude. But i think my point remains, if a word or a specific form of a word is rarely used it becomes ""obscure"" or ""archaic"". Believe it or not, language is defined by the majority of speakers who live in the present day. ""Formulae"" is a particular variant of ""formulas"" that has fallen out of favor, or common usage. Now since Wikipedia is a ""current"" encyclopedia, I don't understand why you feel the necessity to use language from the 1800s. How do I put this delicately... nobody uses this word anymore. Why dont you start an 1800s encyclopedia, and you can use all the various archaic English words. 
  I  would like to appeal this decision if that is possible. Thankyou"
