orang-utan: [17] Malay ōrang ūtan means literally ‘wild man’. It probably originated as a term used by those who lived in open, more densely populated areas for the ‘uncivilized’ tribes who lived in the forest, but was taken by early European travellers to refer to the large red-haired ape that inhabits the same forests. The word may well have reached English via Dutch. [orang-utan etymology, orang-utan origin, 英语词源]
