How is ethnography different from ethnology?

In the field of cultural anthropology, the distinction between ethnography and ethnology is often characterized as follows:

• Ethnography is the descriptive study of a particular human society. It is primarily based on fieldwork, requiring the anthropologist to immerse themselves in the everyday life of the studied group—a method known as participant-observation—to produce a detailed account of that specific culture.12
• Ethnology refers to the analytical and comparative study of cultures in general. While ethnography focuses on the description of a specific group, ethnology uses those descriptions to draw comparisons, analyze cultural patterns, and formulate broader generalizations about human societies.13

Although these terms are distinct in theory, the boundary between them is increasingly viewed as fluid in practice. Because ethnographers inevitably retain cultural biases and must interpret their observations, the process of writing an ethnography is inherently comparative and analytical. Consequently, the formulation of generalizations and the drawing of comparisons have become integral components of contemporary ethnographic work.1
