I searched on the Internet and found the opposite of 'somewhere' is 'nowhere.' 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 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.
