Learning Objective
Will and Shall (Part 2): Promises, Requests and Formal Uses
Recognise how will can express willingness, promises, requests, and refusal, and how shall appears in formal rules.
Clear Explanation
Will can express willingness, a promise, a request, or a refusal with will not. Shall occurs in formal rules and legal-style statements, but it is less common in everyday speech.
Form and Structure
will + base verb; will not / won’t + base verb; shall + base verb
“I will send the revised document this afternoon.”
In formal documents, shall can be ambiguous between obligation and futurity. Use it only when the intended convention is clear.
Meaning and Use
Promises
Will can commit the speaker to a future action.
“I will not share your personal information.”
Willingness and refusal
Will and will not can describe a person or thing that is willing or refuses to act.
“The car will not start.”
Formal shall
Shall may impose an obligation in rules or contracts, although must is often clearer in plain English.
“Applicants shall provide proof of identity.”
Common Errors and Meaning Traps
I promise I shall to help.
I promise I will help.
Use will + base verb for an ordinary promise; do not add to after a modal.
Will you to close the door?
Will you close the door?
Will is followed directly by the base verb.

The negative modal form won’t is followed by the base verb without to.
