Noble or of the valley
Deleah is a modern American name likely created as a blend of the prefix 'De-' with the name Leah, or as a variation of Delia. It carries associations with the Hebrew Leah, meaning 'weary', or the Greek Delia, referring to the island of Delos. In contemporary use, it is often interpreted through its phonetic roots as having a noble or gentle quality.
