The most brilliant name in the history of the world. Cynthias must be intelligent because they have to learn how to spell a difficult name at a young age. As a result, people named Cynthia inspire others, including poets, who refer to the moon as cynthia. The male version of this name is Cynthio, but its not very common. Cindy is a diminutive nickname that is best confined to those who are tall, in order to avoid the saccharin sweet Cindy Brady phenomenon.
