The word "gratuity" refers to a sum of money given to someone for their services or work, often as a reward or to show appreciation. It is commonly associated with tips given to service workers, such as waitstaff, taxi drivers, and hotel staff, for the quality of service they provide. A gratuity is typically voluntary and not mandatory, though it is often expected in certain contexts.
The term "gratuity" originates from the Latin word "gratuitem," which means "freely given" or "favor." This Latin word is derived from "gratus," meaning "pleasing" or "grateful." The use of the word in English dates back to the early 18th century.
