Etymology
Origin of expendable
Explanation
Anything expendable is not necessary — it can be done without. If you lose or use expendable funds, you won't miss the money. None of us wants to be called expendable — that means we could be replaced. If a football team isn't worried about certain players leaving for another team, then those players are expendable: they won't be missed and won't disrupt things if they leave. In war, some people are considered more expendable than others: a soldier is more expendable than a general, because there are far fewer generals. In any country, the least expendable person is the president or other leader of the nation. That's why they get so much protection from their security guards, who are considered much more expendable.
