We use will for an action we intend to do in the immediate future decided at the moment of speaking. It is often used for offers and requests. It is also used for predictions in the future and can be accompanied by “I think”. Because the decision is made at the moment of speaking, sometimes it is not 100% certain, there can be a certain amount of uncertainty (for further info. see going to.) In the negative form we usually use the contracted form won’t To be noted we can use Shall in the interrogative form, but now days will is more commonly used. Nowdays shall is used more as a suggestion.

•  future actions happen without the speaker’s intention
