In the Linguistics lesson on Language varieties, I asked you to be creative in coming up with a research topic into varieties, whether geographical, gender-based, age-based, profession-based, or even individual (i.e. idiolects). An example I gave was investigating differences in the language used by a policeman who stopped an old pick-up and a new Mercedes for speeding (which could be used to critically examine unfairness in the Thai justice system based on privilege).
What is the most creative and interesting research idea for investigating varieties that you can think of, and what would be the purpose or implications of the research?
