devil

The English devil derives from the Old English dēofol, which in turn descends from the Latin diabolus, itself borrowed from the Ancient Greek diábolos (διάβολος). The word thus passed successively from Greek to Latin, from Latin to Old English, and thence into modern usage.

Ancient Greek · διάβολος (diábolos) The Greek term signified "slanderer," "accuser," or "one who falsely accuses." It is worth noting that the modern word began its existence not as a designation for a monster, but as a term for a false accuser.

Latin · diabolus The Greek word was adopted into Latin, where it retained its religious signification.

Old English · dēofol (circa the early medieval period) The Latin-derived term entered Old English through the spread of Christianity—an illustration of language advancing in tandem with belief.

Modern English · devil The spelling and pronunciation gradually evolved into the form current today.

The original meaning The Greek diábolos is related to the verb diabállein (διαβάλλειν), meaning "to slander," "to defame," or "to bring accusations against someone." It is traditionally analysed into two constituent elements:

dia- (διά): across, through, or between

bállein (βάλλειν): to throw

Taken literally, these components suggest a sense akin to "to throw across." The established meaning of the verb, however, was to slander or malign. The modern word devil therefore developed from a term denoting an accuser or slanderer into the designation of the supernatural adversary in Christian theology.

Connection to the Bible The Greek diábolos appears both in the Greek translation of the Hebrew Scriptures and in the New Testament. In Christian usage, it became a title for Satan—the adversary who tempts, accuses, and opposes humanity.

The Hebrew name Satan (שָׂטָן), by contrast, derives from a word meaning "adversary" or "accuser." Although the two terms possess related religious associations, they originate from distinct linguistic roots and ought not to be conflated.
