It operates like many other auxiliary verbs, verbs which are sometimes called conditionals, but which we will call modal verbs. Examples of other modal verbs are can, may, should, or must.
Examples of modal verbs are: can, will, could, shall, must, would, might, and should.
We should list out the different types of verb and words used with examples for class. Easier to access and take look at so that we can reference it. I am starting to create a list of these.
May add to glossary as well.
