-where attaches to five words (some, no, every, any, else) to form a closed set of location adverbs. It only works with these five, you cannot invent other combinations.
somewhere = at/in some place (it exists, but you don't know which) nowhere = at/in no place (fully negates location) everywhere = at/in every place anywhere = at/in any place (free choice, no restriction) elsewhere = at/in a different place (than the one already mentioned)
"I left it somewhere" = it exists, I just don't know where. "I can't find it anywhere" = used with a negative. "Sit anywhere you like" = free choice. "If this store doesn't have it, we'll look elsewhere" = a different place than this one.
some/no/every/any/else + where. Closed set: only works with these five words.

"someplace" and "noplace" exist in informal American English, but general and written English prefers "somewhere" and "nowhere".
"everywhere" does not make the verb plural. Always use "there was" / "it was", never "they was".
"anyplace" is informal American English; "elseplace" simply does not exist. Always use "anywhere" and "elsewhere".
A trick to remember it
