Etymology

genealogy = genea<family, race> + logy<study of>

  • genea: From Greek genea (γενεά), meaning "family," "generation," or "race."
  • logy: From Greek -logia (λογία), a suffix denoting "the study of" or "discourse about."

Etymology Origin:
The word genealogy traces back to Greek genealogia, combining genea (family/generation) and -logia (study). It entered Middle English via Old French genealogie, retaining its core meaning of tracing familial descent. The morphemes reflect a logical progression: genea anchors the concept of lineage, while -logy systematizes it as a field of study. Historically, it emphasized noble or royal pedigrees but now applies broadly to any family history.
