Basics: May and Might - Expressing Possibility

When we want to talk about things that are possible but not certain, we use the modal verbs may and might. For example, saying "I might go to the concert" or "It may rain later" shows that there is a chance something will happen, but you aren't completely sure.

In this challenge, you will practice using these modals in a variety of everyday situations, from predicting the weather and future movie plans to talking about missing cats and ruined picnics. You will explore affirmative and negative forms (such as may not or might not) and practice the essential rule of pairing these modals correctly with base verbs.

You'll work through 12 questions featuring a fun mix of single-choice, multi-choice, drop-down, and drag-and-drop formats.

To ChallengesStart Challenge
Question 1
Help the amateur astronomer evaluate a mysterious sighting.
"That strange light in the sky _________________________ to a UFO! On the other hand, it _________________________ a very bright airplane."

The correct answers are might belong and may just be.

Modal verbs like "might" and "may" do not change form for the third-person singular (no "-s" ending on the modal or the main verb). Even when an adverb like "just" is added, the main verb stays in its base form ("be").

Question 2
Read the anxious picnic planner's thoughts. Select ALL the grammatically correct ways to complete their worry.
I just bought twenty sandwiches, but our friends ______ because of the thunderstorm!

The correct answers are may not come and might not come.

When making "may" or "might" negative, we simply add "not" right after the modal verb (may not / might not). You don't need helper verbs like "don't", and you still must use the base form of the main verb without "to".

Question 3

Choose the best word to complete the nervous picnic organizer's warning.

Look at those dark clouds! I haven't checked the radar, so I'm not entirely sure, but it ___ rain during our lunch.

The correct answer is might.

We use "might" (or "may") to talk about things that are possible in the present or future, especially when we are not 100% certain they will happen.

Question 4
Help the picnic organizer decide what to pack by completing her thoughts.
"Look at those dark clouds! We _________________________ an umbrella, or it _________________________ on our delicious sandwiches."

The correct answers are may need and might rain.

After modal verbs expressing possibility like "may" and "might," we always use the base form of the verb (without "to" or any "-s", "-ed", or "-ing" endings).

Question 5

Help the brave student guess what is inside the mystery cafeteria stew. Drag the correct verb forms into the blanks.

The glowing green stew might contain some sort of chicken. It may also taste exactly like old gym socks, so please proceed with caution!

The glowing green stew might contain some sort of chicken.

After modal verbs like "might" and "may," we always use the base form of the verb (no "-s", "-ing", or "-ed").

It may also taste exactly like old gym socks, so please proceed with caution!

Just like in the first sentence, "may" must be followed by the base verb "taste."

Question 6

Help the indecisive student complete their text message.

I haven't bought tickets yet because they are a bit expensive, but I ___ to the concert this weekend.

The correct answer is may go.

After modal verbs of possibility like "may" or "might", we always use the base form of the verb (the bare infinitive) without "to", "s", or "ing".

Question 7
Help the neighborhood detective list all the grammatically correct possibilities for the missing cat's location. Select ALL that apply.
The sneaky cat ______ hiding under the neighbor's porch right now.

The correct answers are may be and might be.

Both "may" and "might" are perfect for expressing possibility! Remember the golden rule of modal verbs: they must be followed directly by the base form of the verb (in this case, "be"). We never use "to" or add "-s" after a modal verb.

Question 8

Complete the nervous meteorologist's weather forecast by dragging the correct words into the blanks.

The forecast says it might rain tomorrow, so you should probably bring an umbrella just in case. Alternatively, the sun may decide to shine in the afternoon. I really have no idea!

The forecast says it might rain tomorrow, so you should probably bring an umbrella just in case.

We use "might" to show that something is possible but not certain. The verbs "are" and "has" do not grammatically fit before the base verb "rain."

Alternatively, the sun may decide to shine in the afternoon.

"May" is used just like "might" to express possibility. The verbs "has" and "was" cannot be followed directly by the base verb "decide."

Question 9

Help the office detective finish her dramatic conclusion about the missing snack.

The suspect has powdered sugar on his shirt, but he ___ the one who stole my jelly donut. I also saw Steve eating a pastry earlier!

The correct answer is might not be.

To make sentences with "might" or "may" negative, we place the word "not" immediately after the modal verb and before the base verb (might + not + base verb).

Question 10
Complete the exhausted college student's text message. Choose ALL the grammatically correct options that apply.
I had three exams today. I'm so tired that I ______ asleep before the movie even starts.

The correct answers are might fall and may fall.

"May" and "might" are both excellent choices for talking about future possibilities. Even if the sentence feels like it's pointing to the future, you must stick to the base form of the verb ("fall"). Never use the past tense ("fell") or an "-ing" form ("falling") right after a modal verb!

Question 11
Complete the frantic student's realization about his missing phone.
"I can't find my phone anywhere. It _________________________ in my jacket pocket, but I'm not sure. Oh no, I _________________________ have it with me at all!"

The correct answers are might be and may not.

"Might" is followed by the base verb "be" (not "is" or "to be"). To make a modal verb negative, we simply add "not" directly after it (may not / might not). We never use "don't" or "doesn't" with modals!

Question 12

Complete the friends' conversation as they search for their sneaky cat, Barnaby. Drag the correct words into the blanks.

Barnaby might not be hiding under the sofa, because he is way too chubby to fit. On the other hand, he may decide to sleep in the clean laundry basket again.

Barnaby might not be hiding under the sofa, because he is way too chubby to fit.

"Might not" is the correct way to express a negative possibility. "Does not be" and "is not be" are grammatically incorrect.

On the other hand, he may decide to sleep in the clean laundry basket again.

"May" expresses possibility and is followed by the base verb "decide." The other options ("has decide" and "wants decide") are grammatically incorrect because they are missing "to" or an "-ed" ending.

Modal verb

If you've ever struggled with the difference between You must do this (strong command) and You should do this (advice) — or It might rain (possible) and It will rain (certain) — you've felt how much modal verbs do in English. They're how the language signals certainty, obligation, possibility, and politeness, and getting them right is what stops your speech from sounding either pushy or wishy-washy.

A modal verb is an auxiliarycan, could, may, might, must, shall, should, will, would — adding meaning around ability, permission, possibility, obligation, or speculation. Always followed by the bare infinitive (can swim, never can to swim), and never inflected for person.

Questions

If you've ever asked You like coffee? with rising intonation and gotten a confused look — you've felt the gap between casual and grammatical English questions. Many languages form questions with intonation alone, but English usually requires inversion (Are you ready?) or do-support (Do you like coffee?). Skip the structure and your questions sound like uncertain statements.

Questions in English use inversion of subject and an auxiliary (Can she dance?) or do-support when no auxiliary is present (Does the milk go in the fridge?). Yes/no questions, wh-questions, negative questions, and tag questions all share this machinery.

Negation

If your native language uses double negatives (I don't see nothing) — like Russian, Spanish, or French — you've probably been told this is wrong in English and not been entirely sure what the fix is. Standard English uses one negative per clause: either I saw nothing or I didn't see anything, never both. Once you internalise that single rule, your written English clears up a lot.

Negation in English uses not after an auxiliary or modal verb: I am not going. Without an auxiliary, you add do-support (I do not go). Negative words like never and nobody already negate the clause — adding not on top creates non-standard double negatives.

English Grammar Basics

If grammar feels like a tangle of rules you can never quite remember, the fix isn't more advanced material — it's making the foundations automatic. The English Grammar Basics tag is where you do that: the building blocks every other topic stands on. Get these right and the rest stops feeling random.

It marks quizzes and explainers covering the core of English: nouns, verbs, adjectives, adverbs, prepositions, conjunctions, tenses, voice, mood, and basic sentence structure. Useful whether you're a beginner or refreshing rusty knowledge.

A2 | Elementary | Pre-intermediate

If you can order coffee, ask for directions, and tell someone what you did yesterday — but struggle the moment the conversation drifts into anything abstract — you're operating at A2. Knowing this matters: A2 is the level where most learners plateau because they reach for B2 material too early and burn out. Stay here and your foundations get unbreakable.

A2 is the elementary level in the CEFR framework, covering routine communication and the first wave of real grammar: past simple and continuous, present perfect, basic modal verbs, first conditional, and common verb-pattern rules.

Difficulty: Easy

If a textbook leaves you confused, sometimes the issue isn't the topic — it's that the practice material is layered with extra complications. Filtering by Easy strips that away. You get one rule at a time, in plain everyday language, with no trick questions. It's how you make a shaky foundation solid before stacking more on top.

The Easy difficulty tag marks beginner-level questions and challenges — typically A1 or early A2. Single-rule focus, short sentences, common vocabulary, one clear correct answer.
