If you've been paying attention, it's been long established that the Grounders can understand and speak English. Trigedasleng is a secret language they started in order to be able to communicate without their enemies figuring out. That's why they try to hide the fact that they know English from people they can't trust.

So, it's not the language that naturally changed over time.
