Language and Identity

Topic: Language and Identity
Exact topic: The self-portrayl of american politicians vs. british politicians in a TV interview.
Half of the term paper has to be a theoretical part, the second part has to be a practical part. There also need to be speechpart transcripts in the practical part. All sources of those speechparts need to be named in the bibliography.
The points what is identity and how is it related to language should be included in the theoretical part.
I’m also open fpr other suggestions on the topic as long as it has something to do with language and identity 🙂
