Using the hypothetical and non standard word "manywhere"

I have frequently used "manywhere" to describe "many places" instead of "everywhere".

• In increasing order: nowhere < somewhere < manywhere < everywhere

It seems to be an elegant and logical solution to a missing language element, doesn't it? The following fictional dialog demonstrates my thinking. (This is not factual):

• 
  

  "Have you heard about the ritual of hanging a voodoo doll on buildings under construction to keep away negative energy?"

  
  

  "Yeah, I saw that somewhere in my home town of New York City."

  
  

  "Well in India, you can find that manywhere."

  
  

  "Manywhere?"

  
  

  "Yes. That's a logical word I made. Not everywhere. Many places have it! That better describes the meaning, does it not?"

  
  

  "Hmmm. I guess it does. I never really thought about it like that!"

  
  

Manywhere has some modern and historical usage:

So my questions are:

• Why is this missing in English? What if someone wants to say more than somewhere but less than everywhere?


• Are there situations when/where this word could be used?


• What would be good/bad right/wrong effective/ineffective in "introducing" manywhere into standard English? (If one actually could do such a thing.)


• I think it would be a great word! Am I missing something?


• It seems to me that the opposite of somewhere (at some places) is manywhere (at many places) and NOT nowhere. It broadens the scope. Does that make sense?
