=== Submenus
-Submenus in GTK+ are not created by separate type of menu item widget but by calling Gtk::MenuItem#submenu= method. This method calls Gtk::Menu#attach_to_widget to attach the submenu to the menu item and places an arrow beside the menu item to show that it now has a submenu. If the menu item already has a submenu, it will be replaced with the given Gtk::Menu widget.
+Submenus in GTK+ are not created by separate type of menu item widget but by calling Gtk::MenuItem#submenu= method. This method calls Gtk::Menu#attach_to_widget to attach the sub-menu, which is actually a Gtk::Menu object, to the menu item. The menu item which is a sub-menu is marked by an arrow which is placed beside the text of menu item to show that it now has a sub-menu. If the menu item, to which you assign a sub-menu (Gtk::MenuItem#submenu=) already has a sub-menu, it will be replaced with the last Gtk::Menu widget that was assigned to it.
