The article “By Any Other Name: Races of the Underdark, by Owen K.C. Stephens first appeared in DRAGON #281 (March 2001).
It’s first section contains some example prefixes for derro names, but the player is encouraged to mix and match with name fragments from other articles in the series (dwarves, elves) or alternatively combine with the duergar and svirfneblin name fragments on the other tables within the article.
I’ve listed the derro name prefixes here for reference:
Adj– Charmer, leader, ruler
Ari– Dagger, hidden, sword
Diin– Fool, loser, lost
Diir– Lucky, treacherous
Faka– Scout, thief, wisdom
Inka– Savant, wizard
Kara- Cursed, insane
Miirn- Dance, dancer,war, warrior
Sec- Gilded, jeweled, ornamental
Uriin– Poison, tool, weapon
Xeer- Hate, joy, pain
Thus the two main derro deities with names of Diirinka may mean “treacherous wizard” or “lucky savant” whereas Diinkarazan may be loosely translated as “lost cursed brother” and secari is an “ornamental dagger” as described in early derro descriptions.
Other supplements have used other naming conventions with variable consistency, which I aim to compile as a list at some stage as a resource.
