The English modal auxiliary verbs are a subset of the English auxiliary verbs used mostly to express modality, properties such as possibility and obligation. [a] They can most easily be distinguished from other verbs by their defectiveness (they do not have participles or plain forms [b]) and by their lack of the ending ‑(e)s for the third-person singular.
For example, the inferred certainty sense of English must developed after the strong obligation sense; the probabilistic sense of should developed after the weak obligation sense; and the possibility senses of may and can developed later than the permission or ability sense.

It could alternatively be interpreted as a question, "Is it possible for examples of the dance that have been outshone to outshine others?"
By contrast, (5) could be paraphrased as 'Given his abilities, the strength of his teeth, etc., it is possible for John to open a beer bottle with his teeth'. Here, the modal base is defined by a subset of John's abilities, the modal force is possibility. (5) John can open a beer bottle with his teeth.

Modal logic is a kind of logic used to represent statements about necessity and possibility.It plays a major role in philosophy and related fields as a tool for understanding concepts such as knowledge, obligation, and causation.
Examples are the English and French conditionals (an analytic construction in English, [c] but inflected verb forms in French), which are morphologically futures-in-the-past, [1] and of which each has thus been referred to as a "so-called conditional" [1] [2] (French: soi-disant conditionnel [3] [4] [5]) in modern and contemporary linguistics ...
