Opposites Theme Naming

Opposites Theme Naming a variation of Theme Naming using a set of names within a work that create a theme by using words that are opposite to each other or act as foils to each other. Authors like to use themes to create a sense of unity or cohesiveness within their work. Some extend themes to the names of the characters, often beyond the similarities that would be expected for characters from the same culture or who all speak the same language. When the author does this, you have Theme Naming.

Using Opposites Theme Naming puts the named persons in strong contrast to each other. Sometimes it is used to set up the characters as enemies or foils to each other, though it may also signify that they balance each other in a way that is complementary and productive rather than antagonistic. Other times it simply serves to provide symmetry in the names without actually signifying anything about the personalities or relationships of the characters.

This often overlaps with Theme Twin Naming, especially when they are Polar Opposite Twins. Can also sometimes be found in Salt and Pepper set-ups (which trope name is also an example).

 * Lords and Ladies has a character whose mother tried to follow the tradition of naming daughters after virtues, but got very confused about it: her daughters had the names of virtues, so she reasoned that her sons should have the names of vices. Meanwhile, all her children completely lacked the traits they were named for. Her daughters had names like Charity (a miser), Hope (chronically depressed), and Chastity (a lady of negotiable affection). She named her sons after vices, such as Anger (a kind and nonviolent man), Bestiality (very kind to animals), and Deviousness (an honest and straightforward chap).
