It's always "nearby" :-)

This is a great question. It's also a hard one to answer in brief terms, but I’ll do my best! Near and nearby are both synonyms for close. However, there are three clear and important differences in their meaning and use: 1) The first difference is that near is often used as a preposition, but nearby can never be properly used as a preposition. Furthermore, when near is a preposition, it doesn’t simply mean close, it means close to, as shown in this example: I left the box near the door. [near means close to (the door)] I left the box nearby the door. [You may hear someone say this occasionally, but it is not considered correct.] 2) The second difference is that near can mean close in time (=soon), as well as close in distance, but nearby cannot, as shown below: Summer is drawing near. [near=close in time] May is nearby. [nearby cannot mean close in time] 3) The third difference is that nearby can appear either before or after a noun that it describes, but near can normally appear only before the noun, and even then, only when referring to time.* Here are some examples: We slept at a nearby motel. [nearby + noun] We slept at a motel nearby. [noun + nearby] I hope to visit you in the near future. [near + noun, and near=close in time] I hope to visit you in your near home. [near cannot be used before a noun to refer to distance]
