Greek language
Greek was a Human language spoken by the Greek people on Earth. Derived from ancient Greek spoken since the 2nd millennium BC, elements of the language survived as a significant source of Starfleet and Federation nomenclature and terminology. 

Fundamentally, the stellar cartographic quadrants of the Milky Way Galaxy were labeled Alpha, Beta, Gamma, and Delta – exclusively Greek letters. Multitudes of other uses included installations (Epsilon IX station), protocols (evasive pattern delta 5), computer files (Janeway Lambda One), scientific discoveries (the Omega molecule), stars, and planets (Ceti Alpha V) labeled or named with Greek letters.

Captain Jean-Luc Picard was fluent in the Greek language. In 2368, he read the Homeric Hymns in its original language. ()
