The word intramundane describes anything existing or occurring within the physical world, within the bounds of Earth and human experience.
Intramundane comes from Latin roots meaning "within" and "world." This adjective is used to describe things that exist within the physical, earthly realm, rather than things that are supernatural or beyond human experience. For example, the study of ecosystems or everyday human interactions can be considered intramundane topics because they focus on the tangible world.
