Häidi

Häidi is a diminutive of the name Adelheid, which is of Old High German origin. Adelheid is composed of the elements 'adal' meaning 'noble' and 'heid' meaning 'kind, type, or sort'. The name Adelheid was brought to England by the Normans and became popular in various forms, including Adelaide and Alice. Häidi, with its specific spelling, is primarily associated with the Swiss German diminutive form of Adelheid, often spelled Heidi.

The name gained significant international recognition through Johanna Spyri's beloved 1880 novel 'Heidi', which tells the story of a young orphan girl living in the Swiss Alps. This book popularized the name globally and firmly established its association with Switzerland and a cheerful, wholesome, and nature-loving character. While the spelling 'Häidi' is less common than 'Heidi', it reflects a more traditional German orthography, sometimes used to indicate the umlaut sound.
