Definition: The word "elf" has no specific meaning in English or the Bible, but its origins are uncertain. The term "Elf," also known as "Carni" or "Alfe," appears to be a medieval term that originally referred to elves (creatures of mythological origin) who could climb trees and eat human flesh. It's not clear what its precise meaning was before the 19th century, but it's often used in fantasy literature where creatures with such powers are described as "elf-like."
