"Modal verbs" no usan -s en tercera persona, no usasn el verb auxiliar do/does to negativos en forma, preguntas o respuestas cortas, pueden usar contraciones en negativo, pueden usar frases sinonimas. "Modal of advide, necessity, obligation and prohibition" "must and have to" (no es un verb modal) pero parla d'obligació. "needn't and don't have to" (no son verbs modals) no obligació. "need" només en negatiu i en interrogatiu, en afirmatiu s'utilitza "need to" i expressa necessitat. "ought to / should" recomenacions. "had better"intenció, en negatiu es "had better not" "Modals of ability and permission" "can / can't" habilitat en el present, "could / couldn't" habilitat en el passat, "be able to" habilitat en altres temps, "can / can't" permis en el present.
