Master or lord; also a diminutive of Cyrus or Cyril.
Cy is most often used as a short form of Cyrus, which is derived from the Persian name Kūrush, meaning 'lord' or 'young.' It can also stem from Cyril, which comes from the Greek word kyrios, meaning 'master.' As a standalone name, it offers a punchy, mid-century modern appeal.
