Old High German origin
Source-reportedMeaning: “noble” + “character”
Borrowed from Old High German Adalheid, traditionally given as Proto-Germanic *aþalaz (“noble”) + *haiduz (“character”), although the declension and gender match Proto-West Germanic *haiþi (“heath, pasture”) instead. First attested in the 10th C. CE
