Definition of “have to”
“Have to” can be used as an expression of obligation or necessity, whether related to work, school or personal responsibilities. In everyday language it may refer to external circumstances dictating that someone must do something and indicates an external authority is behind this obligation or compelling reason behind any obligation – be that from circumstances, factors or personal responsibilities.
It implies an element of duty, suggesting there exists some external force forcing one into doing it voluntarily or compelling reasons behind any obligation being felt in life and work situations alike. In daily usage “have to” can express obligations related to work, school and personal responsibilities while outlining obligations related to work, school obligations as well as personal responsibilities related to personal responsibilities related to either work/school obligations/responsibilities from either workplace/school related /personal life/personal obligations/etc…
Definition of “must”
“Must” conveys more urgency or obligation than its counterpart “have to.” It conveys more of an imperative than just necessity and should be used when there is personal conviction involved, such as when suggesting something essential or imperative based on personal conviction or strong recommendation.
Where “have to” can indicate external commitment to something or someone, “must” expresses internal conviction with little flexibility available and leaves little space for alternative options – making “must” ideal in formal, serious contexts such as rules, regulations or instructions.
