CIRCLE WITH A DOT

@johncarlosbaez I remember seeing a constructed language for dwarves that had a number of non-human features. One was a lack of pronouns, instead it had a half dozen words that worked as variables. You would mark the antecedent with a certain suffix, and then the chosen word would refer to only that noun for the rest of the conversation. It seemed like a reasonable system to avoid ambiguities like this one.
