will + [subject] + be + [verb-ing]?
The future continuous describes something that will be happening at a certain moment in the future. It started before that moment and will go on after it. It has three parts: will, be and the verb with -ing.
Will is the same for every person. In speech and messages, it becomes 'll. The negative is won't be.
These phrases often go with it, because they name the moment in the future.
Will + base verb is for a decision, a promise or a single action. Will be + -ing is for an action already in progress at that time.
Will you be + -ing asks about someone's plans politely, without asking them to do anything.
Verbs for states, like know, want, like and be, don't use this form.
