Elementary English Grammar - Must and Must Not. Must is a modal verb. You use must to recommend things to do and places to see.
To express there is no obligation you can use do not have to. Or you can use noun must, e.g: There is no such must. Negated form, must not, has different meaning than do not have to. Consider modal verbs: can, may, have to etc. Negative forms of these modals have meaning that there is no obligation.
