How to say "horde" in Japanese

• 群衆ぐんしゅうCommon
  nounCovers the human crowd or throng sense of 'horde': a large mass of people gathered in one place. Best when describing street gatherings, spectators, or onlookers; it does not naturally cover animal groups.

  A crowd gathered at the scene.
• 大群たいぐんCommon
  nounCovers the horde sense built on size and numbers: a very large group. Unlike 群衆 it is not limited to people, matching glosses for large herd, flock, and school of animals as well as a large crowd.
  イナゴが大群たいぐんをなしてやってきた。↗

  Locusts came in big swarms.

Use 群衆 for a horde of people, i.e. a densely packed crowd, and 大群 when the emphasis is on sheer numbers, including large groups of people or animals such as herds and flocks.
