Modals for Permission, Obligation, and Prohibition

Summary

This video is the second in a series focusing on modal verbs and their use in expressing permission, obligation, and prohibition. It explains that modal verbs, such as can, must, should, and have to, alter the form of the base verb to convey these concepts, which differ from usual verb conjugations. The video provides examples and discusses phrases like 'be allowed to' and 'be supposed to' that also indicate permission or obligation. It emphasizes the unique characteristic of modal verbs that the base form of the verb following them does not change, regardless of the subject or tense.
