EXPRESSING SUGGESTION, OBLIGATION & PROHIBITION

Should, could, might and shall are used to express suggestions:

• Shouldn't we have a pizza instead?
• You could talk to your parents and ask them.
• You might consider taking up meditation.
• Shall we throw a party sometime next week?

PROHIBITION

These situations are the opposite of giving permission. This modal verbs for prohibition lesson shows you how to use may and can, to prohibit someone or create rules.

Can’t

Can’t is the most common way to prohibit something in English. It is not as formal as must not or may not, but it is the most common. Here are some examples:

• You can’t drive here.
• You can’t wear a hat in class.
• You can’t smoke in the office.
