For most of the nation’s history, members of the U.S. House of Representatives have been addressed as “Congressman” or “Congresswoman.” By contrast, a senator is referred to as, well, “Senator.” These gendered terms for House members dominate in journalism, everyday conversation and among members of Congress.

“Whereas ‘congressman’ or ‘congresswoman’ tends to call our attention to a House member’s Capitol Hill activities and to his or her relationship with colleagues,” wrote the late Richard Fenno, “‘representative’ points us toward a House member’s activities in his or her home district and to relationships with constituents.”
