A consultant is an expert in a particular field. Sometimes a business will rely on the guidance of a consultant to help change its image.

How did the word consultant come about? Consult dates to the 1520s and comes from the French word consultare, meaning "take advice of." The related noun consultant, to mean someone qualified to give advice, is believed to have first appeared in an 1893 Sherlock Holmes story.
