person from an earlier family generation
A person in your family who lived long ago, such as your great‑grandparents and earlier, from whom you come.
Vzorec užití:
[someone]'s ancestor; an ancestor of [someone]
Častá chyba:
Learners sometimes confuse *ancestor* with *elder* or *old person*. *Ancestor* is not just any old person; it must be someone you are directly related to from an earlier generation. For example, an old neighbor is not your ancestor. Learners also sometimes say "my ancestors from 20 years ago"; usually, *ancestors* are several generations back, not recent relatives like parents.
Synonyma
forebear (Slightly more formal; almost the same meaning, but used more in writing than in everyday speech.)
|
forefather (Usually male and often used for respected or founding ancestors, sometimes in a national or cultural sense.)
Antonyma
descendant (Refers to someone who comes after you in the family line, the opposite direction of an ancestor.)

earlier species in evolutionary line
An older kind of plant, animal, or other living thing from which a newer kind developed over time.
Vzorec užití:
an ancestor of [a species/group]
Častá chyba:
Learners may think *ancestor* in this sense always refers to humans, but in biology it can refer to any earlier life form, including plants, animals, or microorganisms. Another confusion is between *ancestor* and *old species*; a species can be old without being a direct ancestor of another.
Synonyma
progenitor (More formal and technical; often used in scientific writing about the first form of a species or group.)
Antonyma
descendant species (Refers to a later species that comes from an earlier ancestor species in evolution.)

earlier version that led to something
An older type of thing, like a machine or idea, that came before and led to the one we have now.
Vzorec užití:
an ancestor of [a thing/system]
Častá chyba:
Learners sometimes think *ancestor* can only refer to people. In modern English it is also common, especially in writing, to talk about the *ancestor* of a machine, technology, or idea. However, this is still a literal relationship of earlier and later forms, not just anything old.
Synonyma
forerunner (Emphasizes that something came before and prepared the way for what followed; slightly more formal.)
|
precursor (More formal and often used in technical or academic writing for something that comes before and leads to something else.)
Antonyma
successor (Refers to something that comes after and replaces or develops from an earlier form, the opposite direction of ancestor.)
