Modals are a special kind of auxiliary (helping) verb. We use modals to express things such as
  • future time (will)
  • ability (can, could)
  • possibility (may, might, could)
  • necessity (must)
  • advice (should)
The main verb after the modal must be in the simple (root) form. Never use a gerund (Ving) or infinitive (to V) after a modal!
