Demon naming traditions
Demon names in fiction draw on a long documented tradition of grimoires and demonologies, which gives them a distinctive and recognisable sound.
The grimoire sound
Historic demonological texts catalogued named entities — Belial, Asmodeus, Bael, Astaroth, Belphegor, Paimon — and that corpus shaped every fictional demon name since. The pattern is Semitic and Greek-derived roots, heavy on b, l, m, z, th, with -oth, -eus, -el and -on endings. Names built on those sounds read as authentically infernal because readers have met the pattern hundreds of times without ever studying it. The endings do most of the work: take a plausible root, attach one of them, and the name arrives already sounding catalogued.
Names as power is the core convention
In nearly every tradition that names demons, knowing the true name grants leverage over the bearer — which is why grimoires were name catalogues in the first place rather than collections of stories. That gives a demon's name plot function, not just flavour: it is a thing to be hidden, bargained for, discovered and used, and it means a scene can turn on a name being spoken. It also explains why demons in fiction so often refuse to answer the question, and why a character who already knows the answer has power before anything else happens.
Rank shapes the name
The classical demonologies assigned hierarchies — princes, dukes, presidents, legions commanded — with a specificity that reads as oddly bureaucratic to modern eyes. Grander, longer, more ornate names for the higher ranks and short, guttural ones for lesser spirits creates an immediately legible hierarchy in your own setting, in the same way the historic texts did. Readers will infer rank from the name before you state it, which lets you introduce a minor demon and a major one in the same scene without explaining which is which.
Borrow the shape, not the deity
Many classical demon names are the names of other cultures' gods, absorbed and demonised by a rival religion — Astaroth and Baal among them, both originally worshipped deities. Knowing that is useful both for authenticity and for tact: inventing a name in the same phonetic shape gives you the effect without repurposing a deity that people still worship. It also gives you a worldbuilding device with real historical grounding, since a demon who was once somebody's god is a more interesting character than one who was always a monster.

Tips for a name that sticks
Harsh sounds read as evil
Hard consonants and clipped syllables — 'Vex', 'Grimroth', 'Azgoth' — feel more sinister than soft, flowing names. Lean into K, G, TH and Z sounds.
A title tells the legend
'The Devourer', 'Lord of Ash', 'the Nameless' — an epithet hints at what the demon did to earn its reputation. Save titles for named antagonists, not minions.
Keep the true name speakable
Even a dread name gets said every session. Two or three syllables at the core keeps it usable at the table while still sounding ancient and wrong.
