Diminutive of Hazel or Hazard, a playful English pet form with nature associations.
Hazzie is a diminutive of Hazel or Hazard, giving it either a nature-rooted warmth or a more unusual, surname-like edge. As a pet form, it feels playful and affectionate, with the kind of softness that comes from shortening and brightening a longer name.
The Hazel connection is especially appealing because it adds a natural image of trees and color. The name has a cheerful, friendly sound and a lightly vintage feel. It can suggest informality and closeness, as diminutives often do, while still remaining unusual enough to feel distinctive in modern use.
Hazzie sits at the intersection of playful nickname and stand-alone name, which gives it a lively, approachable personality. It sounds warm, spirited, and a little whimsical.
