Final answer:
Language use varies within the same formal language primarily due to geography and situation, but also due to social status and identity. Speech communities and dialects specific to geographical regions or social groups add to this variation. Language serves not just for communication but also as a marker of identity, adapting to fit different audiences.
Step-by-step explanation:
The variance in social language use within the same formal language can be attributed primarily to geography and situation, but also to factors like social status and identity. For instance, certain phrases or ways of speaking may be common in one region versus another due to geographical dialects. Situational context can also influence language use.
Professional settings often demand standard, formal language, while more casual or familiar settings may see the use of vernaculars or slang.Individuals who are part of different social groups or who belong to different socioeconomic levels may also experience variations in their language use.
particularly when they are trying to navigate between different cultural expectations. Additionally, the concept of a speech community illustrates how language can evolve to form dialects that are specific to a particular group or region, which can further cement social identity and group belonging.
Moreover, language is not only a tool for communication but also a marker of identity. People subconsciously modify their language use to fit different audiences, thereby showcasing their multilingual capabilities or cultural backgrounds, as in the case of former U.S. President Barack Obama's strategic language use that helped bridge different communities and subvert stereotypes.
