When to Use “May” and “Might”

The modal verbs “may” and “might” are very common in English and although they have similar meanings, there are some key differences. Understanding when to use “may” versus “might” can be tricky for English learners, so let’s break it down.

Usage of “May”

1. Permission: “May” is commonly used to seek or grant permission. It is often perceived as more formal and polite when compared to “might.”
   • May I use your computer, please? (Seeking permission)
   • You may leave the room now. (Granting permission)
2. Possibility in the Present or Future: “May” is used to express a possibility in the present or future. It indicates that there is a good chance something will happen.
   • It may rain this evening. (There’s a high probability of rain.)
   • She may join us for dinner tonight. (It’s likely that she will join.)

Usage of “Might”

1. Possibility in the Present or Future (with Less Certainty): “Might” is also used to express possibilities, but it suggests a lower degree of certainty compared to “may.” It implies that there is a chance something will happen, but it’s not as likely.
   • It might snow tomorrow. (There’s a possibility of snow, but it’s not very likely.)
   • He might come to the party if he’s feeling better. (There’s a chance he will come, but it’s uncertain.)
2. Hypothetical Situations in the Past: In some cases, “might” can be used to talk about hypothetical situations or possibilities in the past.
   • If he had studied harder, he might have passed the exam. (Hypothetical situation in the past)

Additional Tips

• “May” is often considered more formal and is commonly used in written and spoken language when seeking or granting permission.
• “Might” is used when there is a lesser degree of certainty or when discussing more informal situations.
• In some contexts, “might” can be used to express a sense of caution or skepticism.
• While there are distinctions in usage, modern English allows for some flexibility, and the boundaries between “may” and “might” can be blurred in casual conversation.

May vs. Might: Definitions and Usage

“May” and “might” are part of the category of auxiliary or modal verbs used to express possibilities, permissions, or conditions. Let’s explore their usage further.

Distinction in Degree of Probability

One of the key differences between “may” and “might” is the degree of probability they convey. “May” implies a higher probability, often around a 50% chance of occurrence, while “might” suggests a lesser degree of certainty.

• I may go to the theater. (There’s a relatively greater possibility that I will go.)
• I might go to the theater. (There’s a somewhat lower possibility that I will go.)

Implications in Tense

Historically, “may” was used to express probable current or future events, while “might” addressed hypothetical situations in the past. While modern usage allows for more flexibility in this regard, maintaining this distinction in formal or academic writing can enhance clarity.

Seeking or Giving Permission

In situations involving the seeking or granting of permission, “may” has traditionally been the preferred choice and is often seen as more polite or formal. “Might” is rarely employed in this context.
