Create a character profileHistorical demon names derive from corrupted angel names, Semitic root words, and medieval grimoire traditions. The Ars Goetia catalogs 72 named demons, many ending in -as, -on, or -iel. Fantasy demon names build on this tradition with harsh phonetics that feel alien to human speech.
About demon names
The medieval grimoire tradition produced systematic demon naming. The Ars Goetia, Lesser Key of Solomon, and Pseudomonarchia Daemonum each catalog demons with names derived from corrupted Hebrew, Greek, and Aramaic words. Many established demon names (Astaroth, Belphegor, Malphas) are distortions of pagan deity names absorbed into Christian demonology.
Demon naming conventions vary dramatically by cultural source. Judeo-Christian demons favor corrupted angelic suffixes (-el, -iel, -ael). Japanese oni carry short, percussive names. Hindu and Buddhist demonic beings (asuras, rakshasas) follow Sanskrit naming patterns. Choosing your source tradition shapes the entire phonetic identity of your demons.
Rank matters in demon naming. Greater demons and archdevils tend toward longer, more imposing names with multiple syllables (Mephistopheles, Beelzebub), while lesser demons carry shorter, harsher names. This hierarchy creates a natural naming system where the sound of the name communicates status.
Naming tips
Corrupt familiar sounds
Take a recognizable root word from Hebrew, Latin, or Greek and distort it. "Mal-" (bad), "nox-" (night), or "mor-" (death) combined with unfamiliar endings create names that feel both ancient and wrong. The sense of linguistic corruption mirrors the creature's nature.
Use hard consonant clusters for menace
Combinations like "zr," "kth," "ghr," and "xz" are difficult for human mouths, which makes them feel appropriately alien. Place these clusters at the start or middle of names, not at the end where they become unpronounceable.
Distinguish rank through syllable count
Minor imps and lesser fiends work well with one or two syllables (Grix, Nazh). Mid-rank demons benefit from three syllables (Azeroth, Valmorak). Demon lords and archdevils earn four or more (Asmodethian, Xulgorath). This creates an intuitive power scale.
