| <2> | A demonym is the name for a resident of a community which is usually derived from (or is related to) the name of that community. In other words, it's how the residents of Boulder refer to themselves. It's important to note that there aren't any rules for taking a town's name and turning it into a demonym. A demonym is informal and while the majority of Boulder may use one name, keep in mind that others may use something different. |
