In the English language, a modal verb is a type of auxiliary verb. The key way to identify a modal verb is by its defectiveness (they have neither participles nor infinitives). In addition, modal verbs do not take the inflection -s or -es in the third person singular, unlike other verbs. A modal verb (also modal, modal auxiliary verb, modal auxiliary) is a type of auxiliary verb that is used to indicate modality -- that is, likelihood, ability, permission, and obligation. The use of auxiliary verbs to express modality is particularly characteristic of Germanic languages. Modal auxiliary verbs give more information about the function of the main verb that follows it. Although having a great variety of communicative functions, these functions can all be related to a scale ranging from possibility ("may") to necessity ("must"). Note that dare and need are much more commonly used as non-modal verbs, taking -s or -es in the third person singular and having an infinitive and past and present participles.
