Using this criterion, we generalize about the kind of meanings that words convey. For example, we could group together the words brother and car, as well as David, house, and London, on the basis that they all refer to people, places, or things. In fact, this has traditionally been a popular approach to determining members of the class of nouns. It has also been applied to verbs, by saying that they denote some kind of "action", like cook, drive, eat, run, shout, walk.
