What Does the Name Cy Mean?

Cy is an English short form rather than a name with an ancient root of its own. It is most often a clipped form of Cyrus or Cyril, and sometimes of Cyprian or another name beginning with Cy-, so its sense depends on the longer name it shortens. Cyril comes from Greek Kyrillos, a diminutive of kyrios, "lord," and that line of the name is usually rendered "lordly." Cyrus goes back through Greek Kȳros to Old Persian Kūruš, a name whose original sense is not settled; Greek speakers connected it by folk etymology with kyrios, "lord," a link that is traditional rather than demonstrable. Because Cy is only a clipping, it has no separate meaning apart from the full name behind it.

Cy Name History & Origins

Since Cy is a nickname, its history is largely the history of the full names it clips, and in English it has served mainly as a familiar spoken form rather than a formal name on documents. It shows up that way in American public life: the baseball pitcher Denton True Young was known as Cy Young, and the painter Edwin Parker Twombly Jr. was called Cy Twombly. One traditional explanation for the ballplayers' nickname is that it shortened "Cyclone," though the clipped form has also been understood as standing for Cyrus. Cy is also used directly as a given name in its own right, chiefly in the United States, where it is short enough to stand alone without a longer form behind it.
