we have to get an example of code-switching either between varieties or languages. This example is preferred to be evidenced from a clip of a movie that code switching has taken place in there. We need to indicate which theory is the code-switching taking it’s approach is it using 1) Weinreich 2)Gumperz 3)Myers-Scotton 4)Giles 5)Scotton and Ury ? We need to specify one of the five that we think the code-switching can be best analyzed by there theory(I will provide the reading that explains their theories about code-switching).
