I searched on the Internet and found the opposite of 'somewhere' is '[nowhere](http://wiki.answers.com/Q/What_is_the_Opposite_of_adverb_somewhere?#slide=2).' This confuses me, because I see it like this:

* The opposite of "everywhere" (at all places) is "nowhere" (at no places).
* The opposite of "somewhere" (at some place) in my logic-thinking should be *something like* **"manywhere"** (at many places).
* I know **'manywhere'** is not an accepted English word. But the English construction `{no, some, any, every} + "where"` seems to have left-out a concise and logical way to express "manywhere".

The following fictional dialog demonstrates my questions/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 **everywhere.**"

"What? Voodoo dolls are in *every* construction building in India?"

"No! I mean, you can find that **manywhere**. Many places have it - not every one."

(You see, I don't want to say, "In India, you can find that **everywhere**" because that would mean **every** construction building would have a voodoo doll.)

This question is **not** about "manywhere" which is asked [here](https://ell.stackexchange.com/questions/17546/using-the-hypothetical-and-non-standard-word-manywhere) as a separate question. But it is to help me understand the logic behind the opposite of "somewhere" and how can one discuss "many places" with a lack of a "manywhere-type word". It's not logical to me. What are the various *acceptable* ways to express "many places" as described above? Can I use "many where"? It'll still solve the problem.
