What does the term 'uncouth' mean?

The term 'uncouth' is used to describe someone who lacks manners and social grace. It implies a sense of awkwardness or rudeness in social situations, often associated with behavior that is considered unrefined or vulgar. People described as uncouth may not adhere to societal norms of politeness, leading to discomfort among others in social settings. This aligns perfectly with the definition that emphasizes the absence of sophistication or good manners.

In contrast, the other choices provide characteristics that are either opposite to or differing from the concept of being uncouth. For example, being excessively shy doesn't inherently involve a lack of manners; it's more related to personal disposition and comfort in social situations. Similarly, being highly refined or extremely polite are traits that directly oppose the idea of being uncouth, as they both indicate a high level of social grace and proper etiquette. Thus, the choice that aligns with the meaning of 'uncouth' as lacking manners and grace is the most fitting.
