English modal auxiliary verbs

The English modal auxiliary verbs are a subset of the English auxiliary verbs used mostly to express modality, properties such as possibility and obligation. They can most easily be distinguished from other verbs by their defectiveness (they do not have participles or plain forms) and by their lack of the ending ‑(e)s for the third-person singular.
