Final answer:
Discourses relate to language and social construction by emphasizing the role language plays in shaping social interactions, forming cultural identity, and influencing the dynamics of communication within communities.
Step-by-step explanation:
The notion of Discourses relates to language and social construction by emphasizing the role that language plays in shaping social interactions and cultural identity. As language and culture are intricately linked, the way we use language is affected by cultural norms and, in turn, the language we use shapes our social realities and interactions. We learn and use language in a social context, which forms an essential part of our communal and cultural identity, while our ability to communicate both concrete and abstract ideas is facilitated through grammar and lexicon. Through language, social norms and values are conveyed, challenged, and reinforced within different speech communities.
