contiguous

Imagine building with LEGO bricks—if the bricks are contiguous, they're all touching each other, forming one solid structure. It means sharing a border or being in direct physical contact. You might describe states on a map as contiguous if they share a boundary line, or row houses on a city block as contiguous because they share side walls. Think of it like pieces lined up with no spaces between them.

The word often pops up when talking about land and areas. You can also use it for things in a sequence. For example, a writer might describe the contiguous chapters of a novel—chapters that come right next to each other (like chapters 3 and 4), not chapters separated by several others. It's all about closeness and direct connection.

To say something is contiguous means it's touching, bordering, or connected—not just near, but directly adjacent. The word comes from the Latin contigere, meaning "to touch." Think of a map of the United States: Texas is contiguous with Oklahoma, Arkansas, and Louisiana because they share borders. However, Texas isn't contiguous with California; there are several states in between!

This concept extends beyond geography. People sometimes talk about the "contiguous United States," meaning the connected 48 states (not Alaska and Hawaii). In computer science, contiguous memory refers to blocks of data stored right next to each other in the system's memory—a more efficient way for the system to access information. In geology, contiguous plates refer to tectonic plates that are touching and interacting at their boundaries.

You might also use the term figuratively. A historian could describe two historical periods as contiguous if they followed directly after one another with clear, unbroken connections. Or an architect might design contiguous rooms in a house, creating a sense of flow and openness by ensuring they are physically joined.

While not used in everyday conversation as often as phrases like "next to" or "connected," contiguous adds precision when you need to emphasize direct adjacency and an unbroken link. It's about more than just proximity; it's about shared boundaries and seamless transitions.
