The word anthropology dates back to the late 16th century, but it was not until the 19th century that it was applied to the academic discipline that now bears its name. In the United States, this field of study is typically divided into four distinct branches: physical (or biological) anthropology, archaeology, cultural (or social) anthropology, and linguistic anthropology. Anthropology is from the New Latin word anthropologia (“the study of humanity”) and shares its ultimate root in Greek, anthrōpos (“human being”), with a number of other words in English, such as anthropomorphize, philanthropy, and misanthrope.
