Word History of ORANGUTAN
Orangutans live in dense tropical forests on the islands of Borneo and Sumatra, part of Indonesia. Like most apes they look a bit like humans. In a language called Malay, spoken by many people of Indonesia as a second language, the apes were given a name formed from Malay orang, “man,” and hutan, “forest”—in other words, “man of the forest.” Europeans visiting the islands adopted the word orangutan, and it found its way into English.
