Giulietta is a diminutive form of the name Giulia, which is the Italian version of Julia. The name Julia itself is derived from the Roman family name Julius, which is believed to be related to the Greek word 'ioulos', meaning 'downy-bearded' or 'youthful'. Giulietta carries connotations of youth and vitality, and is often associated with beauty and grace, partly due to its literary associations with Shakespeare's Juliet.
