The Need to Learn by Doing

A student recently asked about the differences between need to, have to, and must. Sometimes an explanation clarifies such doubts, but often one learns much better through practice with some feedback. If you’d like short sets of tasks to study differences in structure and meaning, check out my Need to.Have to.Must_handout.

Key points include:
– Need to expresses what is important and what one feels should be done.
 Have to and must express what is necessary or what is required by some authority.
– Need to and have to agree with the subject.
– Must doesn’t change forms to agree with the subject.
– Have to and must can be used to express a personal desire.  (Examples: I simply must know! You just have to come to the party!)
