Etymology tree
Forms
diabolus m (genitive diabolī); second declension[1] Also diabulus (Old Latin Bible, Jerome, Augustine) and zabulus, zabolus (Lactantius, Commodian, Augustine); medieval dyabolus, diablus.[2][3][4][5]
Etymology
It is borrowed from Ancient Greek διάβολος (diábolos, “slanderer, accuser”),[1][3][6] a noun from διαβάλλω (diabállō, “to slander”), a compound of διά (diá, “through, across”) and βάλλω (bállō, “to throw”).[1]
Isidore of Seville explains the name twice: in Hebrew it means “flowing down”, because the Devil fell from heaven, and in Greek “accuser”, because he accuses the innocent before God.[7][5] The Romance words for “devil” continue it, among them Italian diavolo.[8]
Earliest recorded meaning
It is a word of Christian Latin.[8][3] The first author to use it is Tertullian, for a devil and for the Devil.[9][6][4]
Semantic evolution
In Bible translations and the Church Fathers it is the Devil, Satan, and also any demon or evil spirit.[9][10][5] Medieval writers kept these senses and applied the word to wicked people and, by metonymy, to disaster and ruin.[5] It entered plant and mineral names: morsus diabolī, “devil's bite”, for the devil's-bit scabious, and in alchemy dentēs diabolī for sal ammoniac.[5] In British sources the Devil appears as tempter, in possession and in curses, from Gildas and Bede on.[11]
