What is the Difference Between May Might and Could?

The modal verbs "may," "might," and "could" are used to express degrees of possibility, but they differ in terms of formality and likelihood. Here are the key differences between these three modal verbs:

1. May:

• Formal usage
• Used to express actions that are more likely to happen
• Can also indicate permission or requests (e.g., "You may leave whenever you like")

1. Might:

• Informal usage
• Used to express actions that are less likely to happen
• Can also be used as the past tense of "may" (e.g., "Might" can be used as the past tense of "may," and "could" is the past tense of "can")

1. Could:

• Can be used to refer to past actions and to express ability
• Considered a polite form

While "may" and "might" are often used interchangeably when referring to probability, "could" is typically used to express a lower degree of certainty or to describe ability. For example:

• "The package may arrive tomorrow." (More formal and likely)
• "The package might arrive tomorrow." (Less formal and less likely)
• "The package could arrive tomorrow." (Less certain and polite)

Additionally, "might" can be used as the past tense of "may," while "could" is the past tense of "can". For example:

• "She might have left earlier." (Past tense of "may")
• "She could have left earlier." (Past tense of "can")
