Which term refers to a person who is new at something?

The term "novice" specifically denotes a person who is new to a particular activity or field. It captures the essence of someone who lacks experience or has just begun their journey in a given area. This recognition of being new or inexperienced is critical, as it implies a level of learning, growth, and development ahead for the individual.

The other terms suggest varying degrees of skill and experience that do not align with the definition of someone just starting out. An expert is someone who possesses a high level of knowledge or skill in a specific area, while an experienced person has gained proficiency through practice and time spent in their field. A professional typically refers to someone engaged in a specific vocation, often with formal training and derived expertise. Therefore, "novice" is the term that accurately portrays the condition of being new at something.
