Apocrypha

 * In Diane Duane's novel The Romulan Way, the Romulan language is said to be related to the Vulcan language. This suggests that during the Exodus of the Romulans, they abandoned most things Vulcan.

In order to rectify this problem, the Romulans went back to old or "High" Vulcan and "aged" the language in another direction.
