It's often used in words to indicate something complete or encompassing the whole, such as:
* Hologram: A three-dimensional image that appears to be a complete object.
* Holodeck: A fictional device from Star Trek that creates complete, immersive environments.
* Holotype: A single, preserved specimen that is considered the definitive representation of a species.
* Holistic: A way of looking at things as a whole, rather than in parts.
