In the game League of Legends, the character Vi is known for her violent, aggressive, fight-loving nature, and isn't shy about expressing it. When asked what her name is short for, she has a different response each time, with each relating to this nature.
"Vi? Stands for Violence!!"
"Vi? Stands for Vice!"
"Vi? Heh... stands for Vicious!"
Beyond being a humorous joke, is the fact that these words have a similar theme more than a coincidence? Is vi a root word or prefix that has some meaning which causes this relation? Are there other words that begin with vi- that also fit this theme?
