Bonjour

I had to change   ► obligation      // passé

I had to hike the PCQ ► obligation  //  passé

Cheryl will have to  ► obligation   // futur

Do you have to wear  ..?  ► absence d'obligation // présent

You don't have to bring back ► absence d'obligation // présent

phrase affirmative = sujet + have + to

phrase interrogative = have + sujet + to

phrase négative = Sujet + have + not + to

conclus

obligation  : have + to

absence d'obligation = don't + have + to

interdiction = mustn't

n'oublie pas que à la 3e personne du singulier have = has au présent
