Which term refers to someone who is dazzlingly skilled in a particular field?

The term that refers to someone who is dazzlingly skilled in a particular field is "virtuoso." A virtuoso is someone who possesses a high degree of skill or artistry, particularly in the context of music or the performing arts. This term conveys a sense of exceptional talent and mastery, indicating that the individual stands out in their field due to their remarkable proficiency and creative expression.

In contrast, the other terms describe varying levels of experience or skill that do not reflect the same level of expertise. An amateur is someone who engages in a pursuit without professional skill or knowledge, while a novice refers to a beginner or someone who is just starting to learn something new. A layperson is someone who is not a professional or expert in a specific field, lacking the high level of skill that characterizes a virtuoso. Thus, "virtuoso" is the most appropriate term for an individual known for their dazzling skill.
