Qual é a diferença entre offspring e children ?Podes indicar apenas respostas exemplo.

The words essentially mean the same thing, however, "offspring" sounds more "technical" or clinical." In this sense, the relationship of the words "offspring" and "child" is similar to the relationship of the words "wife/husband" and "spouse," or the relationship of the words "brother/sister" and "sibling."
Typically, we use the word "offspring" to refer to animals, rather than people, but it is also possible (but rare) to use it to refer to people.
An example of it being used to refer to people is the movie "Star Wars: Return of the Jedi" where Obiwan it telling Luke Skywalker about the fact that his father is Anakin Skywalker (who became Darth Vader).
"The Emperor knew, as I did, if Anakin were to have any offspring, they would be a threat to him."
