What does "eloquence" refer to?

Eloquence refers to the skill of using language effectively and persuasively. It embodies fluency in speech or writing, allowing an individual to express their thoughts and emotions in a clear, engaging, and impactful manner. Someone who is eloquent is often able to articulate complex ideas in a way that resonates with their audience, making the communication not just clear, but also enjoyable and compelling.

In contrast, the other options reflect attributes that are the opposite of eloquence. A lack of expressiveness, confusion in speech, and harshness in dialogue all emphasize communication deficiencies, which do not align with the concept of eloquence. Thus, the correct definition of eloquence as fluency in language highlights the ability to communicate with grace and effectiveness.
