I like to read the various series wikias and guides as I go through a series I'd seen before, to pick up on stuff I may have missed. I ran across this on The Lurker's Guide to Babylon 5 for A Voice in the Wilderness, Part 1:
I tried to develop a basic language structure for each of the races on B5. There are certain commonalities to the structure of names. I came up with some prefixes and suffixes, and assigned meanings to them, the same as real names. For instance, Rathenn (referred to by Delenn in "Voices") and Delenn have the same suffix, which has a specific meaning. You can break it down; Ner-oon (Legacies), Del-enn, Rath-enn, Der-onn, and so forth. The various parts do have specific meanings, but I generally keep that to myself, just for amusement.
Narn names follow a similar pattern, which I suspect has something to do with which Narn religion they/their parents followed. I remember thinking the
G' in G'Kar's name may be because he's a follower of G'Quan, but it would also fit with G'Lan, so I'm no longer sure. (And if that were so, why would G'Quan and G'Lan's names follow the same pattern as modern Narn, anyway..?)
Has J. Michael Straczynski, the creator of Babylon 5 and who the quote above is from, ever revealed the meanings of all these prefixes/suffixes?
