You may as well try to explain why cats have four legs. It's just the way things are in the world. You might offer the encouragement that all modal verbs act the same way ( will, would, can, could, shall, should, may, might, must ) and have the additional advantage of having only one form.

  • You never have to add "s" or "ed" to any of them.
  • And there aren't very many of them.
