After telling my students the other day in tutorial that must and have to have the same meaning, one of them proceeded to argue the point. He had been taught - or had read somewhere, he isn't sure where - that must implies a stronger obligation than have to and therefore it has a slightly different meaning. After citing several examples, I gave up trying to convince him that there is no difference between the two.

Could the grammarians in the room please give me your opinion(s)? Is there a difference, however subtle, between must and have to or are they synonymous?

You are right.

I don't doubt that your student read that distinction somewhere, but who knows where.

I read somewhere that the difference (or a difference) is in whether the obligation is internally or externally imposed. For example, a student could say of him/herself, "I have to study," whereas a teacher could say either "You must study" or "you have to study."

You are correct in the postive sense. It is only when we negate these that the real difference is apparent.

Must not ... is not the same as Don't have to ...

That is the grammatical explanation, although intuitively I feel that 'must' does carry more weight and obligation than 'have to'. Grammarians will not agree with me on this.

I kind of agree with your student actually. They have the same 'meaning' but not the same usage (which amounts to a different meaning in my book).

Must is more imperative, or more serious.

"We must rid the country of neo-nazis."

Have to or Got to seems a little less formal, or just 'normal'.

"I have to get this done by tomorrow."

I am a little surprised if you can't sense this as it seems quite obvious to native speakers!

The difference between "must" and "have to" - I would borrow Denise's words: Internal or external obligation.

"Must" is internal, i.e. in your mind you accept it even if it is an imposed obligation from someone else; "have to" looks more like an obligation you can't escape - you may obey in spite of yourself, or in spite of moral objections.

I'd go with the external / internal distinction.

If you say "You must....", the authority for this obligation comes from you, the speaker.

If you say "You have to...", the authority for the obligation doesn't come from the speaker, but comes from an external source, such as goverrnment rules, or company regulations.

For this reason, if you wanted to tell someone what to do, but didn't want to be too direct as that person was someone you didn't know too well, you could couch the obligation as a "have to". It would make it sound a little more gentle.

"You must make a note of how many photocopies you make" (a little direct, because I'm telling you)
"You have to make a note of how many photocopies you make" (less a personal command, more a general rule)

I'll go along with the internal/external thing too.

Having said that, in all but written multiple choice exams, teh distinction is almost irrelevant.

Greetings,

Nearly all of my students have been taught that "must" is stronger. It's really quite difficult to get them out of the habit, especially as in Turkish there is really only one wa
