Anthropology is the study of human beings, their behaviors, cultures, and societies. There are a number of synonyms for anthropology, all of which relate to the study of human beings. Sociology is one such synonym, although it often focuses more on the structure of social systems and institutions. Ethnology is another synonym, which more specifically focuses on the analysis of specific cultural groups, their languages, and their customs. Archaeology, on the other hand, investigates the material remains of past societies. All of these fields are related to anthropology in some way, as they all seek to better understand the human experience and the ways in which we interact with the world around us.
