    Note

    Behind the club member stands a body. Belonging to a group is pictured as being one limb of it, which is why the bodily sense sits so close by. The usual construction is member of, though context often lets the noun stand alone, as in Roberta Rogow's "one of the members upstairs."

In geology a member is a rock unit within a larger formation, as in Kenneth J. Englund's "lower sandstone member of the Pocahontas Formation" (1979). The rare synonym integrant stresses the same idea: a part that helps make the whole what it is.
