* Beautiful: Possessing beauty.
* Beautify: To make something beautiful.
* Beautician: A person who specializes in making people beautiful.

It's worth noting that while "kallos" has a clear connection to beauty, the "kal" root is more versatile. This is because it reflects the concept of being pleasing, which can be extended to things like "good" or "pleasing to the mind," as seen in the word "kalendar" (calendar).
