Can a word be contracted twice (e.g. “I'ven't”)?
I would like to know if it is proper to chain multiple contractions into a single word when they are in a continuous string.
For example: "They are not ants." You have the choices: "They're not ants." and "They aren't ants." How about: "They'ren't ants."
If this case doesn't suit your fancy, feel free to suggest a more appropriate example.
