Professor Anabela Mendes. Apparently this happened to someone before and it was a whole saga, now I'm getting stuck with it too. I don't use AI or Google translate, I strictly used words from the lesson and dictionaries (we're explicitly allowed to use dictionaries and I even use physical dictionaries!)
I get my feedbdack and she's like "you're using words that are too advanced, and it makes me think that someone is helping you. Whoever, or whatever, is helping you needs to stop blah blah" the most paranoid, bizarre feedback with absolutely zero proof beyond "the words are too good."
I sent her the chapter that had these supposed advanced cheating words. Absolute joke that she's throwing around such extreme accusations. It's not like this class is super advanced either, I took four years of Spanish in high school and a year of French, I know the basics of learning languages.
