contiguity

Imagine building with blocks. If two pieces are contiguous, they're right next to each other, with no space between them. That's the core idea behind contiguity—things being close together, often physically touching. But it doesn't apply only to objects. Contiguous scenes in a story can come one right after another, and contiguous events can happen back-to-back with no gaps. Think of floor tiles: each tile sits directly beside the next.

The word comes from the Latin contiguus, meaning "touching," so it highlights a direct connection. You won't use this word for things that are far apart, but you might hear it in geography (like the 48 contiguous U.S. states) or in psychology, where contiguity can help explain how we link things that happen close together in time or space.

Contiguity refers to the state of being close together, especially by sharing a physical boundary. It's more than just "nearness"; it implies direct contact or immediate succession. Think of the 48 contiguous U.S. states—connected on the map—unlike Alaska and Hawaii, which are not connected to the rest.

While often used in a literal sense—describing landmasses, buildings next to each other, or objects touching—contiguity can also be applied figuratively. In literature or storytelling, contiguous events happen one right after another without interruption, creating a smooth narrative flow. A writer might describe "a contiguous series of unfortunate events" to emphasize that there was no breathing room between them.

The concept is important in several fields. Geographers use it to define borders and regions. Psychologists explore how contiguity helps us learn; we often associate things that happen close together in time or space (like Pavlov's dogs associating the sound of a bell with the arrival of food). Philosophers have also debated its role in understanding the relationship between cause and effect.

The word carries a sense of connection, unbrokenness, and immediacy. It's not simply about being near something; it's about being directly linked to it. So next time you see things touching or events unfolding seamlessly, remember the power of contiguity—that fundamental principle of closeness and connection.
