- Distant: It means far away in space, time, or relationship. For example, "The two cities are distant from each other", indicating that there is a significant space between the two cities, which is the opposite of being adjacent where things are close together. In a more abstract sense, we can say "Their views are distant from each other", meaning their opinions are far apart and not close or adjacent in terms of similarity.
Other related words that can be considered antonyms to some extent include "separated", "remote" and "apart". "Separated" emphasizes the state of being divided or set apart, like "The two areas are separated by a river". "Remote" also implies a great distance or being far off, such as "The remote village is hard to reach". "Apart" suggests a distance or separation between things, for example, "The two houses are far apart". These words all convey the opposite meaning of "adjacent" which emphasizes closeness and contiguity.
