What does atavic mean?
Atavic is a formal adjective used to describe traits, instincts, fears, or behaviors that appear to be inherited from remote ancestors — echoes of the distant past surfacing in the present. It derives from the Latin atavus, meaning a great-great-great-grandfather or remote forebear, and entered English through scholarly and scientific writing in the nineteenth century alongside the related nouns atavism and atavist. In biology, atavic describes the occasional reappearance of an ancestral characteristic in an organism after generations of absence, such as an unexpected trait in a bred animal. More broadly, writers use it figuratively to characterize deep-seated human impulses — an atavic dread of darkness, say, or an atavic attachment to land — implying that modern behavior is shaped by ancient inheritance. The word carries a literary, slightly dramatic register and is most at home in essays, criticism, and historical or psychological discussion rather than casual speech.
Of, relating to, or characteristic of a remote ancestor; marked by the recurrence of ancestral traits or instincts.
"An atavic suspicion of outsiders lingered in the community long after the reasons for it were forgotten."

Etymology of atavic
Atavic comes from the Latin atavus, meaning a remote ancestor, specifically a great-great-great-grandfather — formed from atta ('father') plus the suffix -avus denoting ancestry. The adjective was borrowed into English in the nineteenth century, largely through scientific and scholarly usage, alongside the noun atavism, which biologists coined to describe the reemergence of ancestral traits. Its closest relatives in English are precisely these sibling terms, all tracing back to the single Latin root atavus.
