The word "spatial" refers to anything related to space or the arrangement of objects in that space. It can describe how things are positioned or how they relate to one another in a physical environment. When we talk about spatial awareness, for instance, we imply the ability to understand where you are in relation to other things around you.
The word "spatial" comes from the Latin word "spatium," which means "space" or "extent." It entered the English language in the late 19th century, primarily used in scientific contexts to describe relationships within physical dimensions.
