Hattie is traditionally an English feminine nickname for the name Harriet, long used independently. It is a diminutive form of Harriet, which itself is derived from the name Henriette, a French feminine form of Henry. The name Henry originates from the Germanic name Heinrich, meaning 'home ruler' or 'ruler of the household.' Hattie has been used as a standalone name and is associated with warmth, familiarity, and a sense of tradition.
