The word genealogy is derived from two Greek words: genea, which means "race" or "family," and -logia, which refers to a "theory" or "science". Together, these roots form a term that signifies the science or study of tracing ancestry and family history.12

Historically, the term entered the English language via Middle English genealogie, which was adapted from the Anglo-French genealogie and the Late Latin genealogia.1
