@lizardsquid The best one I ever came up with was for a particularly group>individual-minded dwarven society.
They referred to people by the largest group they represented, only getting more specific if there was a need to differentiate between individuals. So a typical name structure would be Species Nation City District Clan Given. If someone was the only human in the room, they'd just be called "Human."
And then you introduce membership in organisations, and things get really complicated.
@lizardsquid I really loved those dwarves. They also covered everything they made with intricate patterns that were encoded with information. So their complex names were somewhat simplified by the fact that their clothes and armour effectively had their names, titles and deeds written on them. Dwarven streets would be engraved with their names and what could be found on them, while shop fronts would describe the nature of the businesses they contained.
