Sumerology is a relatively new term that refers to the study of Sumerian culture, history, and language. As a result of this relatively new development, there isn't an extensive list of synonyms for this term. However, some possible alternatives might include Sumerian studies, Mesopotamian studies, or ancient Near Eastern studies, depending on the focus of the research. Another possible synonym could be Assyriology, which primarily deals with the study of the Assyrian civilization and culture but often overlaps with Sumerology due to the political and cultural interactions between the two civilizations. Regardless of the term used, the study of Sumerian culture and history is a rich and fascinating area of research that offers insights into some of the earliest human civilizations.
