This name derives from Old High German name Adalhaid / Adalhaidis, composed of two elements: “*aþalaz” (noble, nobleman, aristocratic, eminent, glorious, excellent one) plus “*haiduz” (kind, sort, appearance, personality, character, manner, path). In turn the name means “noble kind, of the noble sort”. Some forms such as Adel or Heide represents the pet form of names ending in “-heid” (often Adelheid) or beginning with “Heid- / Heide-“. Princess Adelaide of Saxe-Meiningen was the queen consort of the United Kingdom and of Hanover as spouse of William IV of the United Kingdom. Adelaide, the capital city of South Australia, is named after her. Adelaide of Italy (931–999), also called Adelaide of Burgundy, was the second wife of Holy Roman Emperor Otto the Great and was crowned as the Holy Roman Empress with him by Pope John XII in Rome on February 2, 962.
