What is "Shall" in English Grammar?
Shall is a modal verb that is primarily used in British English. Historically, it was commonly used as the first-person alternative to will for talking about the future (e.g., I shall arrive tomorrow).
In modern, everyday English, its usage has shrunk significantly. Today, shall is almost exclusively used in question form with I and we to make offers and suggestions. In highly formal, legal, or policy writing, shall survives to express strict obligation for a third party.
Because it is a modal verb, shall never takes an "-s" and is always followed by a bare infinitive (the base verb without "to").
"Shall" Structure and Formula
In modern contexts, you will almost always use the question structure with I or We.
Standard Formula:
- Offer/Suggestion: Shall + I/We + base verb + Object?
- Formal Future: Subject + shall + base verb + Object
- Formal Negative: Subject + shall not (shan't) + base verb + Object
Pedagogical shorthand:
- (?) Shall + I/we + V(bare) + O?
- (Formal +) S + shall + V(bare) + O
How to Form "Shall" Sentences
Making Offers and Suggestions (Questions)
This is by far the most common use of shall in modern conversational English (particularly in the UK and Commonwealth countries).
| Modal | Subject | Main Verb (V_bare) | Object/Complement |
|---|---|---|---|
| Shall | I | carry | those heavy bags for you? |
| Shall | we | start | the meeting now? |
Formal Future and Obligation (Declarative)
Used almost exclusively in legal contracts, formal rules, and very traditional writing.
| Subject (S) | Modal | Main Verb (V_bare) | Object/Complement |
|---|---|---|---|
| The tenant | shall | pay | rent on the first of the month. |
| We | shall not | surrender | (Famous historical usage). |
(Note: "Shan't" is the contraction of "shall not", but it is extremely rare outside of very traditional British literature).
When to Use "Shall" in English
Because shall has a very narrow application today, it is easy to master.
1. Offering Help (Shall I...?)
Use this to politely volunteer to do something for someone else.
- You look freezing; shall I close the window?
- Shall I make us a cup of tea?
2. Suggesting a Shared Activity (Shall we...?)
Use this to propose an action that includes both you and the listener. It is essentially a more polite version of Let's...
- Shall we go for a walk along the river?
- *It's getting late; shall we* leave?
3. Creating Legal and Formal Obligations
If you are writing a binding contract, a contest rulebook, or an official policy document, shall is used to mean must.
- All participants shall wear safety equipment at all times.

Common Signal Words for "Shall"
- For offers: I can see you're struggling, let me help, shall I...

How to Tell the Difference Between "Shall" and Similar Grammar Topics
"Shall I" vs. "Will I"
- Shall I...? is an offer to help. (Shall I open the door for you? = Do you want me to do this?)
- Will I...? is a genuine question asking for a prediction about the future. (Will I be rich one day? = What do you predict?)
"Shall" vs. "Should" for Suggestions
- Shall we...? directly initiates an activity together. (Shall we go to the cinema? = Let's go to the cinema).
- Should we...? asks for advice or an opinion before making a decision. (Should we go to the cinema tonight? I'm not sure if we have time. = What is your opinion?)
"Shall" vs. "Must" in Contracts
In legal language, they mean essentially the same thing (strict obligation). However, traditional "legalese" vastly prefers shall. In modern "plain English" legal drafting, there is a strong movement to replace all shalls with must to make rules clearer for average readers.

Frequently Asked Questions
Is "shall" completely dead in American English?
In everyday speech, nearly. Most Americans would say, "Should I open the window?" instead of "Shall I open the window?" or use "Let's..." for suggestions. However, Americans absolutely still use shall in legal documents, and they universally understand the phrase "Shall we?".
Can I use "shall" as a strong promise?
Yes. Sometimes speakers use shall to make an incredibly dramatic and resolute promise about the future, completely locking in their commitment (e.g., Cinderella saying, "I shall go to the ball!" or a general saying, "We shall overcome this."). Again, this is highly dramatic and theatrical.
