Expert Answer:

The verbs can, could, will, would, shall, should, may, might, must, and ought are verbs which help other verbs to express a meaning. These are called modal verbs. 
  • Modal verbs are NEVER used with other auxiliary verbs such as do, does, did etc. 
  • The negative is formed simply by adding "not" after the verb. 
  • Questions are formed by inversion of the verb and subject.

Could you pass me the salt and pepper, please?
  • You can never add an "-s" or "-ed" to a modal verb to change its form.
  • Except for ought to, modal verbs are NEVER followed by to

Modal verbs are used to express doubt, certainty, possibility and probability, obligation and permission (or lack of these)

I hope the above information helps.
