"A modal verb is a type of auxiliary verb that is used to express modality, which is the speaker's attitude toward the likelihood, desirability, or necessity of the action or state expressed by the main verb."
"In English, the most commonly used modal verbs are 'can', 'could', 'may', 'might', 'must', 'shall', 'should', 'will', 'would', 'ought to', and 'need'."
"Modal verbs do not usually change their form; they are used in their base form (infinitive) with the exception of 'ought to', which is the only modal verb with a different form."
