Both the Wildwood and Duskwight Elezen are proud clans from a proud race. The forenames and surnames used by them have changed little since the time when they first crossed into Eorzea from the north. However, over the ages, due to bad blood between the two tribes, the surnames once commonly used by both, have been claimed by one side or the other. Now, you will find that while the structures and spellings of the names are extremely similar, and they follow the same phonetic rules, a Duskwight and a Wildwood Elezen will never have the same last name.
The spelling and phonetic rules are extremely similar to those of French, and while there are no set-in-stone guidelines for male or female names, there are some distinguishing features.
Female names tend to end in “ne,” “ette,” or “elle” or on extended vowels like “ie”, and be shorter than the male names.
Male names are longer, and will end in x, such as ‘loix’ (pronounced ‘lo-ah’) or ‘aux’ (pronaounced ‘oh’), or end in a silent t, such as ‘mont’ (pronounced ‘moan’) or geant(pronounced ‘john’).
One will also notice that some of the Elezen names appear familiar to those of the Hyur.
Louis vs Louisoix
Eugene vs Eugenaire
Arthur vs Arthurioux
Gwen vs Gwenolie
Hilda vs Hildie
There are Eorzean historians who believe that these similarities in names may be proof that the two races are of similar origin─’open-minded’ Hyuran historians claiming the Elezen are a bastard race spun off from the Hyurs (and not the other way around). Elezen historians, on the other hand, simply deny any blood relation whatsoever.
