Note: This term refers literally to “the person assigned to carry the standard, or flag, of a group, especially of a military organization,” or figuratively “the leader or chief representative of a movement, political party, etc.” “Standard” is a big flag on a pole, an emblem or symbol of an army or kingdom. The bearer is someone who bears the weight of the flag, which necessarily is tall and big, so that soldiers from a distance will be able to see the flag and follow it.
