Derivation is fancy word for the origin or root of something.

Derivation is most often used in reference to abstract concepts — such as words, names or ideas. The derivation of the word derivation is the Latin derivationem, meaning "a leading off or turning away from." For the origin of more physical things, we tend to use root or source: "Stanley wasn't looking for the derivation of the Nile; he was looking for its source."
