We had a little discussion on monster names in angband on angband.live

[Pete Mack]

Summary:
Sil has some good names for demons, using appropriate Sindarin words+Rauko (demon). In angband (and particularly in FA) there are a bunch of demons derived from DnD that could be renamed appropriately.
Heleg = ice (Gelugon) (Sil uses Ring(a) (as in Ringil), meaning cold.)
Aithorn = lightning (Pazuzu)
Lhîw= disease (Osyluth)
Sangwa, hloima=poison
https://www.elfdict.com/w/blood any number of names for blood or Gore

Also, makes little sense to have both Fury and Erinyes (original Greek name) for different demons.

Here is an outline of my policy for monster name changes in the revamp of the monster list for 4.2. The D&D demons I basically deemed to be sufficiently traditional to Angband now that they should stay.

Note too that erinyes were actually replaced by furies for precisely that reason

[Pete Mack]

Fair enough. But the option is still there for FA.

[Nick]

Yes, good point.

[wobbly]

Oh if we are talking about FA as well I found:

"Maeg Loboth" - sharp rabbit

[Pete Mack]

Anyway, I am making a list

achas - dread
batho - to trample (reaper) (bathoth= trampling) or critha- reap v. (from criss-- slice n.)
baug,buaglir = tyrannous, tyrant
dagnir - slayer, bane ;degant--slay v.
deleb - horrible, abominable
