Research Papers / I need help finding a topic for my research paper (Intro to Linguistics class) [6]

I don't know if this is the right place or not.

Ok, I am in an Intro to Linguistics class (undergraduate) and I have this paper that I have to come up with a topic real soon.

It's some type of research paper that I have to come up with my own theory about linguistics.

I need help real bad. My teacher won't help me at all with choosing a topic, no list, no suggestions. She only approves or disapproves the topic. I have given her 9 topics so far and she has shot all of them down. I need a help finding a topic by Monday or else the highest grade I will make in the paper is a "B".

I have never written a paper like this before. I usually just grab resources and try to write what the people from the resources with my own words. I never made my own theory and I am new to linguistics. I only know a little bit about this subject. (Hello, this is an INTRO class)

The paper has to be something about linguistics. (Not Language Acquisition) I have to write a 9-12 pages about it with 10 resources. I am not asking people to find resources, I just need help finding a topic for my paper/ help making a new theory.

PLEASE HELP!!!!! 70% of my final grade is this paper.

Thanks in advance!
