We went to Europe last year and went everywhere: Berlin, Paris, London, and Madrid.
When I shop for shoes, I like to look everywhere.
I've looked everywhere in the house and still can't find my glasses.
All the usexes look adverbial to me. DCDuringTALK 20:00, 5 December 2010 (UTC)
They look adverbial to me too. Combining two prepositions into one (e.g., "everywhere on", "everywhere at", "everywhere in"...) looks suspect to me... The fourth usex in particular couldn't possibly be a preposition. —AugPi(t) 20:45, 5 December 2010 (UTC)
This looks a new-fangled zero preposition, suitable for a supplementary category, not a PoS header. I had the same problem with nowhere. DCDuringTALK 21:01, 5 December 2010 (UTC)
Changed back from ===Preposition=== to ===Adverb===. —RuakhTALK 13:31, 7 December 2010 (UTC)
