Adeliah as a Baby Name. Meaning and Origin of Adeliah

What is the meaning of the name Adeliah ?

The baby name Adeliah is a Female name , 4 syllables long and is pronounced ah-DEH-lee-uh.

Adeliah is Germanic in Origin.

Adeliah is a modern feminine given name that likely fuses Adelia - itself from Adela/Adele, rooted in the Old High German adal, “noble” - with the -iah ending familiar from Hebrew names. The core meaning remains “noble,” while the -iah finale lends a biblical cadence; in this spelling it is usually decorative rather than a true theophoric “Yah” element. Adeliah sits near Adalia (a biblical name in Esther) and Delilah in sound, which has encouraged contemporary adoption.

In records, the form appears sporadically in 19th‑century U.S. usage as an embellished variant of Adelia and has seen a quiet revival in English‑speaking countries amid interest in vintage choices and -iah endings. Variants and related forms include Adelia, Adélia, Adaliah/Adalia, Adeliya, and Adaliyah, with nicknames Addie, Ada, Della, and Lia. Cognate connections tie it to Adele, Adela, and the Italian/Spanish Adelia, though Adeliah itself remains distinctive and rare.
