  • For legal information, writing instructions and offering rules, must is preferred.

Ex: Cell phones must be turned off during exam. (This is very important and must be followed as a rule)

  • Mostly, adults use “must” when they talk to children about rules.

Ex: You must wash your hands before eating something.

  • Have to is commonly used in question rather than must.
