extinction

In most everyday conversations, this word refers to animals or plants disappearing forever from the Earth. It is usually used as an uncountable noun in this context. When used in psychology or finance (like paying off a debt), it is a more specialized term and sounds very formal. You will mostly see these uses in textbooks or legal documents.
