Adjacent vs. Adjoining: What's the Difference?

Edited by Huma Saeed || By Sara Rehman || Published on January 30, 2024
Adjacent refers to lying near or close to but not necessarily touching. Adjoining refers to touching or contiguous to.

Key Differences

Adjacent refers to something being next to or near another object, with an emphasis on proximity rather than physical contact. Adjoining, however, implies that two objects are not only near each other but also share a common boundary or are touching.

In usage, adjacent can describe areas, buildings, or objects that are close to each other but not necessarily connected. For example, two houses can be adjacent without sharing a wall. Adjoining rooms or buildings, in contrast, are connected directly, like hotel rooms with a common door.

When describing spatial relationships, adjacent suggests closeness but allows for some separation or intervening space. Adjoining conveys a stronger sense of connection, often indicating that there is no physical barrier between the two entities.

Adjacent is often used in broader contexts, such as in geography or planning, to describe the relative positions of objects or areas. Adjoining, on the other hand, is typically used in more specific contexts where direct contact or connection is a key aspect.

In terms of usage flexibility, adjacent can be used metaphorically to describe ideas or concepts that are related but not necessarily directly connected. Adjoining is less likely to be used in a metaphorical sense, as it implies a direct and physical connection.
