What is stronger must or have to?
Then, what is difference between must and have to?
Both modal verbs can be used when talking about obligation. “Have to' is more common, especially in North America, but in the UK there is a subtle difference: 'must' is used for internal obligation and 'have to' is used for external obligation.
Additionally, should have VS must have? "Should have" would mean that the person you are talking to did not tell you about the party, while "must have" would mean that the person you are talking to did tell you about the party.
One may also ask, have to VS must grammar?
Have to mainly expresses general obligations, while must is used for specific obligations: I have to brush my teeth twice a day. I must tell you something. Important: To express obligation, duty or necessity in the future or the past, must and need are not used.
What is the difference between shall and must?
Shall and must. Use “must” not “shall” to impose requirements. “Shall” is ambiguous, and rarely occurs in everyday conversation. The legal community is moving to a strong preference for “must” as the clearest way to express a requirement or obligation.
