English Grammar
Obligation & Advice
must / should / have to + base verb
"Must" and "have to" express strong obligation — with a key difference: "must" usually comes from the speaker, "have to" from an outside rule. "Should" gives advice or a recommendation. Getting this right is essential for sounding natural and appropriate in English.
Real Examples from Native Speakers
