Writing

Modal Verbs of Prohibition

The rules below look different from imperatives.

First, each rule has a subject. The writer names someone or something that is prohibited from doing an action. YOU doesn’t mean one single person. YOU is plural here. It means all the people at the county meeting.

Identify the subject in each rule. The answers will turn blue when you click them.

Second, each rule uses NOT between two verbs. If NOT was missing, these rules would be obligations rather than prohibitions.

Identify NOT in each rule. The answers will turn blue when you click them. The first one has been done as an example.

Third, in front of NOT is a modal verb. A modal verb shows the mood of the writer or speaker. In these rules, the writer has power or status to prevent action. MUST, SHOULD, OUGHT TO, and CAN show that there is no choice. These modal verbs make the rules strong and direct.
