Forming Questions and Negations with Modal Verbs
Modal verbs are unique in forming questions and negations since they don’t require the auxiliary verb do.
Questions
To form a question, simply invert the subject and the modal verb:
- Example: Can you help me? (Not: Do you can help me?)
Negations
To form a negation, add not after the modal verb:
- Example: She must not be late. (Or: She mustn’t be late.)
