Which term describes someone who travels frequently for work?

The term "itinerant" accurately describes someone who travels frequently for work or is nomadic in nature, moving from place to place. This word derives from the Latin "itinerare," which means "to journey," emphasizing the transient lifestyle associated with such individuals. Itinerant workers often have roles that require them to go to different locations, such as consultants, salespeople, or field service technicians.

The other terms do not share this specific connotation. "Impetuous" refers to acting quickly and without thought or care, lacking the notion of travel. "Judicious" denotes having or showing good judgment, which also does not relate to the concept of traveling frequently. Lastly, "lament" means to express sorrow or regret, which has no connection to the idea of traveling for work. Thus, "itinerant" is the most fitting word for someone who frequently travels due to their job.
