terrapin
Terrapin (noun) means any of several small turtles found in various parts of the world.
Etymology
Came from torup (“snapping turtle native to North America, especially the common snapping turtle (Chelydra serpentina)”), or from its etymon Powhatan *tōrəp (“sea turtle”), possibly with English -ine (the suffix forming derivative or diminutive nouns), perhaps influenced by Latin terra (“dry land; soil; planet Earth”). It is cognate with Abenaki tolba (“turtle”), Penobscot dolba and Unami (pisëla)tulpe (“soft-shelled turtle”).
