Shall
Shall: forms
Affirmative form
Shall comes first in the verb phrase (after the subject and before another verb). We use it mostly with I and we:
- I shall post it to you tomorrow.
Shall cannot be used with another modal verb:
- I shall have to be at the airport by 5 pm.
- Not:
I shall must be… orI must shall be…
Shall can be followed by have to, need to and be able to:
- We shall have to tell him what happened.
- The good news is I shall be able to join you at your meeting next week.
Negative form
The negative form of shall is shan’t. We don’t use don’t, doesn’t, didn’t with shall:
- I shan’t be home tomorrow night.
- We shan’t know the result of the tests till Tuesday.
We can use the full form shall not in formal contexts or when we want to emphasis something:
- [a public notice in a restaurant]
- The management shall not be responsible for damage to personal property.
We don’t often use the negative form.
- Modal verbs
Question form
The subject and shall change position to form questions.
We don’t use do, does, did. The question form, with I and we, is the most common use of shall:
- Shall I come round to the office?
- Not:
Do I shall come round to the office?
We use shall in question tags:
- I’ll phone you later, shall I?
Shall: uses
Offers, suggestions and advice
We use shall I and shall we to make offers and suggestions, and to ask for advice.
offer | Shall I carry your bag? |
suggestion | Shall I call again on Thursday? |
seeking advice | What shall we do with this? |
Predictions and intentions
We use shall instead of will with I and we in rather formal contexts to make predictions and to talk about intentions or decisions. It is much less common than will.
Compare
formal | less formal |
We shall remember this day forever. | We will remember this day forever. |
We use shall only with the first person pronouns I and we to make predictions or express intentions:
- The new business cards will be ready at the end of the month.
- Not:
The new business cards shall be ready at the end of the month.
Commands
In very formal contexts, we use shall to give commands:
- [public notice]
- This door shall be kept closed at all times.
- Will and shall
- Commands and instructions
Shall: typical error
We use should, not shall, for advice and suggestions:
- In my opinion, we should book another hotel.
- Not:
In my opinion, we shall book another hotel.
- Should
- Suggestions
