<mrg> #Marain, the Culture's quintessentially wonderful language (so the #Culture will tell you), has, as any schoolkid knows, one personal pronoun to cover females, males, in-betweens, neuters, children, drones, Minds, other senient machines, and every life-form capable of scraping together anything remotely resembling a nervous system and the rudiments of language (or a good excuse for not having either). Naturally, there are ways of specifying a person's sex in Marain, but they're not used in everyday conversation.
