Modal Auxilliaries or Helping Verbs used to be full-time verbs a long time ago. The word, "modals" came from 'mood'. Modals express a lot of moods we have in English. You have necessity, ability, politeness (asking and gving permission), certainty, uncertainty, etc.
These modals make the English language more colorful.
Let's take a look at :
MUST versus HAVE TO
form: MUST + SIMPLE VERB FORM (SVF)
HAVE TO + SVF
Both of them express NECESSITY; however, they are quite different from each other.
MUST - talks about NECESSITY, particulary referring to OBLIGATION. This is stronger than 'have to' because the one that is told must do something and has little freedom to say 'no'.
e.g. All Korean men must undergo military service.
(This is an obligation given by the South Korean government to their male citizens.They cannot say no.) (This is true in South Korea)
You must do your homework now.
(If you don't, you will be in big trouble in school or at home.)
HAVE TO - talks about NECESSITY, NOT obligatory. This one demands that someone does something, but that someone has more freedom of saying 'no'.
e.g. All Korean men have to undergo military service.
(This is not an obligation for them. They can avoid doing it if they want.)
You have to do your homework.
(You can do it later when you feel like doing it.)
