Match the rank
An archdemon needs a heavy, grand name. An imp can have a short, silly one.
Use harsh sounds
Letters like z, x and k give a name an edge. Soft sounds suit a tempter instead.
End fallen angels in -el
Angel names often end in -el, as in Azazel or Samael. Keep the ending to hint at a fall.
Learn from old lore
Old texts name demons like Asmodeus, Belial and Mammon. Borrow their sounds, not the names, for a fresh villain.
Give it a true name
In folklore, knowing a demon's true name gives power over it. A secret name can drive a whole plot.
