Idioms
Usage
What’s the difference between may and might? May and might can both be used as auxiliary verbs (helping verbs) that express possibility, as in We may/might have some left—let me check. Traditionally, might is considered a weaker form of may—meaning that it expresses a lower degree of possibility that something will happen. Some people might intend to use the two words this way, but in practical terms they are often interchangeable when used in this sense—they usually mean just about the same thing. May and might can also both be used in the context of permission, often as what’s thought to be a more polite substitute for can, as in May/Might I use your restroom? In responses to such questions, it’s usually may that’s used, as in Yes, you may. Saying might in such responses is often meant to make fun of such a use of the word in a way that’s sarcastic or that introduces a condition, usually one that’s not serious, as in Yes, you might, if you knew the password. May is sometimes used to express a wish, as in May you have success. Might is sometimes used to express advisability, as in You might ask before you barge in, you know. In its auxiliary verb sense, might can also be used as the past tense of may. It may seem strange to express possibility in the past tense (now that it is known whether or not something happened), but there are plenty of cases in which it makes sense to do it, such as when it’s still uncertain whether or not something could have happened, as in He might have had a chance to become CEO, but he decided to retire early or She might have come if you had actually invited her. Of course, the word may can also be used in the same way to indicate past tense (She may have come if you had actually invited her). Here’s an example of may and might used correctly in a sentence. Example: We might have been able to go today if it hadn’t rained, but in any case we may try to go again tomorrow. Want to learn more? Read the full breakdown of the difference between may and might.

Etymology

Origin of may2
First recorded before 900; Middle English mai; Old English mæg
Origin of May3
First recorded before 1050; Middle English, Old English Maius, from Latin, short for Maius mēnsis “Maia's month”; see Maia ( def. )
Explanation
While may most often appears as a helping verb to indicate that something is possible or allowed, it can also be a noun for a kind of shrub or small tree, also called a "hawthorn." The may has flowers that can range from white to red, and it's also got deep red berries. Since it has a pretty flower that blooms in the spring, it's associated with the month of May. In the 17th-century poem by Robert Herrick, titled "Corinna's Going A-Maying," Corinna is gathering the flowers of the may tree, a springtime activity that goes back as far as medieval times.
