What does terrapin mean?
Terrapin is a chiefly North American name for a freshwater turtle, especially one of the pond turtles commonly seen in lakes, marshes, and slow-moving streams. The term can refer more broadly to turtles in regional or historical writing, but it is most recognizable as the common name for members of the family Emydidae and for the diamondback terrapin. In everyday use, a terrapin evokes a small or medium-sized turtle with a broad shell; it should not be treated as interchangeable with the more specifically terrestrial tortoise. Terrapins are ecologically notable because they occupy both aquatic and nearby terrestrial habitats and often bask on logs or banks. The word also has a prominent cultural life: the Maryland Terrapins take their name from the state reptile. For general readers, terrapin provides a more specific alternative to the very broad word turtle while retaining a familiar regional character.

Where does terrapin come from?
The English word dates to the 17th century, appearing in early spellings such as tarapin and tarrapin. It was borrowed from an Algonquian language, commonly associated with the Delaware region, in a term meaning “turtle”; the precise source dialect remains uncertain. Cognate turtle-words occur in Western Abenaki and Mi'kmaq as well.
How terrapin is actually used
The term is common in North American English but is not a precise taxonomic rank. It most often suggests a freshwater member of the pond-turtle family, whereas capitalized “Terrapin” may also function as a proper name or refer to the Maryland sports team.
