Meaning and origin of Heidy
Heidy is a German name that means “form of Heidi; noble type”.
Heidy is a variant of Heidi, which began as a German and Swiss pet form of Adelheid, the source of Adelaide. Adelheid combines Germanic adal, "noble," with heit, "kind" or "type," so the name is often glossed as "of noble kind." Heidi became famous through Johanna Spyri's children's novel about a girl living with her grandfather in the Swiss Alps. The Heidy spelling is used in parts of Latin America and among Spanish-speaking families in the United States. It keeps the cheerful, wholesome sound of the original, HY-dee, while looking a little different on paper. It is short, sunny and easy to pronounce in many languages.
