Jetta

Jetta is a Dutch feminine given name, functioning as a short form of Henrietta, which itself derives from the Old French and Medieval Latin Henrieta, a feminine diminutive of Henri (Henry). The root traces back to the Old High German name Heimirich, composed of the elements heim, meaning home, and rih, meaning ruler or power. The name has been used primarily in the Netherlands and Scandinavia. Related forms include Henriette, Hette, and Jet.
