Definition of aquatic

The word "aquatic" has its roots in Latin. The Latin word "aqua" means "water", and the suffix "-tic" is derived from the Greek suffix "-τικός" (-tikos), which forms adjectives meaning "pertaining to" or "relating to". Therefore, the Latin word "aquaticus" means "pertaining to water" or "relating to the water". The word "aquatic" was later borrowed into Middle English from Old French "aquatique", which means "of or relating to water". In English, the word has been used since the 15th century to describe something related to or living in water, such as aquatic plants, animals, or activities. Today, the word "aquatic" is widely used in various contexts, including biology, ecology, and outdoor activities.
