How would you describe someone who is "ardent"?

Describing someone as "ardent" conveys a sense of strong emotion and enthusiasm. The term originates from the Latin word meaning "to burn," which metaphorically reflects a passionate intensity. Therefore, when someone is characterized as ardent, it indicates they are deeply enthusiastic, fervent, and often exhibit a zealous commitment to their interests, beliefs, or passions. This word is commonly used to paint a picture of someone who approaches their pursuits with energy and a heartfelt drive, which aligns perfectly with the notion of being very enthusiastic and impassioned.

Other options describe traits that contradict the lively spirit conveyed by "ardent." Calm and collected suggests a cool demeanor far removed from passion, while indifferent and unconcerned implies a lack of interest or enthusiasm entirely. Reserved and hesitant denote a more cautious or reticent personality, which also contrasts dramatically with the vivacious and spirited nature of an ardent individual.
