Other forms: vicinities
If something is in your vicinity, it's in the surrounding area or nearby region — it's in the neighborhood, so to speak. If there's a garbage dump in your vicinity, you'll certainly smell it.
The noun vicinity evolved from the Latin vicinitas, which means “of or pertaining to neighbors or a neighborhood.” Not until 1796 did the word expand in meaning to also describe a “surrounding district.” Said American author Washington Irving, “A kind heart is a fountain of gladness, making everything in its vicinity freshen into smiles.” Slang for vicinity include neck of the woods and turf.
