How to Use Modal Auxiliary Verbs Correctly

- Modal auxiliary verbs do not change form according to the subject. For example, “She can swim” and “They can swim.”

- Using the auxiliary verb “do” with modal auxiliary verbs in questions, negatives, or emphatic statements. For example, saying “Do you can swim?” instead of “Can you swim?”
