Modals of Volition

Modals of volition are a type of modal verb that express a speaker's willingness, intention, or determination to do something. They are often used to make promises, threats, offers, or refusals.
The most common modal of volition is will.
 * I will help you. (promise)
 * I will not tolerate this behavior. (threat)
 * I will help you with your homework. (offer)
 * I will not go to the party. (refusal)
Other modals that can be used to express volition include shall, would, and be going to.
 * Shall I open the window for you? (offer)
 * Would you like me to help you? (offer)
 * I am going to finish this project tonight. (intention)
The choice of modal can depend on the speaker's attitude, the level of formality, and the specific context. For example, will is generally more informal than shall, and be going to is often used to express a strong intention or determination.
Modals of volition can also be used to express other meanings, such as prediction or habit. For example, the sentence "It will rain tomorrow" is a prediction, not an expression of volition.
