Overview
'May', 'might', and 'could' express future possibility with different degrees of certainty. 'May' suggests a real possibility (around 50%). 'Might' implies lower probability. 'Could' suggests a more remote or conditional possibility. None of these express certainty about the future.
May / Might / Could
- mightMight = less certain: It might rain later.
- mayMay = 50/50 possibility (more formal): She may apply for the job.
- couldCould = possible option: There could be delays.
- willWill = confident prediction: Prices will rise.
Degree of certainty
- 100% → will: The sun will rise tomorrow.
- 60% → may: She may get the promotion.
- 40% → might / could: It might snow tonight.
- All followed by base verb (no 'to', no '-ing').
Common Mistakes
