Chapter Other means of expressing modality


Certain verbs have meanings close to the meaning of the modals. They allow us to express opinion, to state a judgment, to impose an obligation.

When stating an obligation, we can use « have to ». Its use is close to the modal « must ».
We use « have to » when the obligation does not come from the person who speaks.
You have to clean your room. In this case we inform the person that he/she is obliged to clean the room, but we are not the source of this obligation.
In return, in the sentence «You must clean your room », it is the author of the sentence who gives the order.

Be attentive, « mustn't » and « don't have to » do not have the same meaning.
« Mustn't » indicates an interdiction while « don't have to » stresses upon the fact that we are not obliged to accomplish an action.
You mustn't touch the paints.
You don't have to go to school.
