Which sentence uses a form of burn or wake correctly?

Erklärung

Burned is a standard past simple of burn, so "The stew burned slightly at the bottom of the pan" is well formed, and burnt would be just as good there. The morning sentence follows didn't with a past form, although the auxiliary already carries the tense and calls for the base wake, and burnted stacks a regular ending on a form that is past already, which English never does.
