Final answer:
Dwight Schrute teaches Erin Hannon the fictitious language of Dothraki from Game of Thrones as part of a comedic element in The Office. This act is an exaggerated portrayal of speech communities and touches on code switching in a humorous context.
Step-by-step explanation:
The fictitious language that Dwight Schrute teaches Erin Hannon on the television show The Office is Dothraki, a constructed language spoken by a community in the Game of Thrones series. Speech communities involve groups of people who share a common language or dialect, while code switching is the practice of moving between variations of languages or different languages in different contexts. For example, a child might use informal language or slang with friends but switch to a more formal language at a school presentation.
In the context of the show, Dwight’s use of Dothraki with Erin was intended as a comedic element, illustrating his quirky and unusual approach to mentorship and friendship. It's an exaggeration of the concept of speech communities, as Dothraki is not a language anyone would naturally speak in a workplace setting. However, it does play on the idea of shared language creating a sense of belonging and identity, even in a fictional context.
