Might and may
Introduction
That might be the solution to our problem.
Definition
May and might are modal auxiliary verbs with different uses.
Construction
affirmative: subject + 'may/might' + bare infinitive I might/may attend.
negative: subject + 'may/might' + not + bare infinitive I might/may not attend.
interrogative: 'may/might' + subject + bare infinitive Might you attend? May I help you?
['might' is very formal in questions and rarely used.]
Note that like other modal auxiliaries, may and might have no infinitive and we use the same form with 'I', 'you', 'he', 'she', 'it', 'we' and 'they'. 'Do' is not used to form negative or interrogative sentences.
Uses
| Use | Example |
|
Polite requests |
May I borrow your pen please?
|
|
Offers | May I help you? Might I take your coat? [very formal, rarely used] |
|
Possibility now [See note 1. below about interrogative forms.] |
The report may be on the printer. Susan might be in the canteen as she is not in her office. |
|
Possibility in the future
|
It may rain later so take your umbrella. John might speak at the conference instead of David. |
|
Permission Might is very rarely used. You may still hear it on very formal occasions or read it in literature.
|
May I use your telephone?
|
|
Might is also used for criticism or reproach.
|
You might help me rather than watching me struggle! |
Notes
1. Rather than using might in questions about possibiity, it is more common to use 'Do you think..?' For example:
| "Do you think you'll go to the conference?" is better than...
|
Might you go to the conference? |
| "Do you think that John has a new girlfriend?" is better than...
| Might John have a new girlfriend? |
We use could for questions about possibility:
May John have sent it in the post instead of by email?
Could John have sent it in the post instead of by email?
2. If there is a chance that may could be understood as permission, then we use might. For example:
Susan may go to the party. [permission or possibility]
Susan might go to the party. [possibility]
3. If you are in doubt about which modal to use:
Use can to express ability.
Use might to express possibility.
Use may to ask for or express permission.
‘Might’/‘may’ or ‘could’ for possibility?
When talking about possibility, might/may and could are not always interchangeable because could has two meanings:
1) 'Can achieve - able to be done or achieved, or able to exist'
The three words are not interchangeable when we are talking about possibility in this way:
"We could play tennis today" means that all the right conditions exist - we have enough time, we have a tennis court nearby etc. We have the ability to play if we want to.
"We might/may play tennis today" means that we are considering playing tennis but we are not sure.
2) 'Not certain - that might or might not happen'
Here, they are interchangeable. In these sentences, we could also use 'maybe' or
'perhaps'.
For example, the following sentences all have the same meaning - there is a possibility
that John is in the boardroom:
John could be in the boardroom.
John might be in the boardroom.
John may be in the boardroom.
Maybe John is in the boardroom.
Perhaps John is in the boardroom.
Different levels of certainty or doubt can be expressed by changes in the tone of voice used.
The present continuous
Might and may can also be followed by the present continuous for possibility now or in the future. For example:
They may be having lunch now; it's half past twelve.
Gilbert might not be driving to the airport tomorrow - his car isn't reliable at the moment.
When using might and may with the simple tenses, it is easy to see if the speaker is referring to the present or the future. For example:
Susan might be in the canteen. [present]
John might speak at the conference. [future]
With the continuous, it might not be clear. For example:
John might be speaking at the conference. [present or future?]
If necessary, we add a time reference.
John might be speaking at the conference at the moment.
John might be speaking at the conference later.
Examples
Do you think that one might suit me?
They might be finishing the meeting soon so I'd better finish my coffee.
We might have to put an extra fire door here to comply with regulations.
May I recommend the dish of the day?
"May I have one more? You certainly may not!"
