Understanding how to express possibility in English is essential for sounding natural in everyday conversations. The modal verbs may, might, and could allow you to talk about things that are possible but not certain, and knowing the subtle differences between them will give you more control over what you communicate.
What do may, might, and could mean?
These three modal verbs share a common function: they indicate that something is possible, but not guaranteed [0:10]. Consider these examples:
- Bonnie may visit this week. — It's possible she visits, but there is no confirmation.
- The company might open a new office. — There is some possibility, yet nothing is decided.
- The store could close tomorrow. — Closing is an option, but nobody is sure it will happen.
In all three cases, the speaker is not making a definite statement. Instead, they are presenting a scenario that has some chance of occurring.
What is the difference between may, might, and could?
Although the three words overlap significantly, there are degrees of possibility you can associate with each one [1:05].
How likely is something with may?
Using may suggests that the event is likely to happen. For example, Jenny may arrive soon communicates that her arrival is expected, though still not confirmed.
When should you choose could?
Saying Jenny could arrive soon implies that it is less likely than with may [1:25]. The possibility exists, but the speaker has less confidence about the outcome.
Is might the least certain option?
Yes. Jenny might arrive soon expresses that her arrival is possible, but no one is very sure [1:37]. It sits at the lower end of the certainty scale.
Here is a quick summary of the degrees:
- May — likely, but not certain.
- Could — less likely.
- Might — possible, but nobody is very sure.
Does the difference really matter in real conversations?
Here is the practical truth: many native speakers use these three words interchangeably [1:52]. In everyday speech, swapping one for another won't create a huge misunderstanding. So if you ever feel unsure about which one to pick, know that any of them will work.
One additional distinction worth remembering is formality [2:10]. May is considered much more formal than might or could. If you are writing a professional email or speaking in a formal setting, may is the safest choice. In casual conversations with friends, might and could feel more natural.
Practice creating your own sentences. Think about different possibilities in your life and try using all three modals. Share your examples in the comments and notice how the level of certainty changes with each word.
