Podcast 1 — Introduction & meaning

Narrator: Today's word is "Posterity" — noun, pronounced /pɒˈsterəti/, with the stress on "pos".

Narrator: Posterity is all the future generations of people who will live after us.

Narrator: In plain English, posterity means the people of the future, the ones who come after us.

Narrator: It comes from the Latin posteritas, meaning future generations, from posterus, meaning coming after.

Narrator: "For posterity" describes keeping something so that future generations can see or read it.

Narrator: It differs from the future because posterity specifically means future people, whereas the future is everything that is yet to come.

Narrator: "A record for posterity" is a phrase for something saved so that people in years to come can learn from it.

Narrator: History, archives, museums, conservation and family life all rely on the word posterity.

Narrator: So remember: posterity means future generations, from the Latin for coming after.
