Hello.
>> Hello. Who are you? >> I'm Ms. Modal. >> What? No, you're not. I'm Ms. Modal. You're Ms. Phrasal Modals. >> I am? I am. How did you know? >> Your modals are different

and be able to, they all have to. >> You're right. >> Well,
your modals are similar to my modals, because when you're with a verb,
the verb stays in the original form. For example, they run,
becomes they have to run. >> I see. But actually, I would call you Ms.
Fake Modals. >> Fake modal? Why? >> Well, for have to,
have got to, and be able to, the modal changes
depending on the subject. For example, when you change the subject
from they to she, have changes to has. She has to run. >> I see. >> Okay.
