He wants to know the name given to the term when you use, like, the name of an inanimate object to describe a person or a group of people. For example, in court you don't say "the judge", you say "the bench", and at a meeting you refer to the person in charge as "the chair". The Prime Minister is sometimes referred to as "10 Downing Street" and the president of the USA is "The White House". That kind of thing.
Anyone know?
