We learn the meaning of a word either by seeing it defined in terms of words already known to us or by experiencing examples of its use and sensing the common properties of the examples. For instance, consider these statements: “Snerd is a member of the country club,” “This saucer belongs to my dinnerware set,” “Fromage is one of the French nouns,” “Points A and B are on the perpendicular bisector of angle α,” “The assault on the western flank was a key element of Varnish’s battle plan.” In each of these assertions something is said to be a member or element of some collection or set of things. As the examples suggest, sets are of wildly different sorts and, accordingly, “membership” can have a variety of meanings.
