The word marsupial traces back to the Latin marsupium, meaning "pouch." This reflects the defining feature of marsupials—their abdominal pouch, where offspring complete their development. The suffix -ial was added in Modern Latin (marsupialis) to form an adjective, later adopted into English as a noun for the animal group. The term highlights the biological uniqueness of these mammals compared to placental or egg-laying species.
