Cosmo

Cosmo belongs to the name family of Cosmas and Italian Cosimo, from Greek kosmos. The word’s range includes order and the ordered world or universe, which explains the name’s later cosmic associations. Its background is older than the modern English use of cosmos for outer space.

Saints Cosmas and Damian, traditionally remembered as physicians, gave the name family an important Christian connection. Cosimo also appears in the history of Florence through members of the Medici family. More recent listeners may recognize Cosmo from the characters in Seinfeld or The Fairly OddParents. These references sit beside, rather than replace, a long history connecting the name with Greek vocabulary, religion, and Italian naming traditions.
