8.3 Obligation/Necessity—Must and Phrasal Modals MUST
PHRASAL MODAL
EXPLANATION
The landlord must provide smoke detectors.
The landlord has to provide smoke detectors.
We use must and have to for rules and obligations. Must is more formal than have to.
I’ve got to call my landlord today. I have to tell him about a problem in my bathroom.
We use have to or have got to for personal obligations or necessities.
At the end of my lease last June, I had to move. I had to find a bigger apartment.
Must has no past form. The past of both must and have to is had to.
Notes: 1. Have got to is usually contracted with a subject pronoun. I have got to = I’ve got to He has got to = He’s got to 2. We don’t use have got to for questions or negatives. 3. Many legal documents use shall for obligation. If the security deposit does not cover the cost to repair any damages, the tenant shall pay the additional costs to the owner. Pronunciation Note: In informal speech, have to is often pronounced “hafta.” Has to is often pronounced “hasta.” Got to is often pronounced “gotta.” In informal speech and writing, people often say or write “gotta.” (I gotta go now.)
