ESL Grammar
Here is a rule that surprises a lot of learners: whether you say a or an depends on sound, not spelling, which is why it is a European but an hour. English grammar is full of small rules like that, and these ESL grammar quizzes give you steady, low-pressure practice with them.
Articles, Verb Tenses, and Sentence Patterns
The sets move through the grammar that trips up learners at every level. You will fill blanks with a, an, the, or no article, drill irregular verbs like begin becoming began and begun, and slot the right form into sentences across past, present, and future tenses.
Later quizzes sort active from passive voice, weigh modal verbs like can, must, and might, and settle the -ing versus to puzzle in pairs like enjoy swimming against plan to travel. Each item gives you a full sentence, so the right choice comes from real context.
Small Words, Big Differences
A few verbs change meaning entirely depending on the form that follows. To stop doing something means you quit it, while to stop to do something means you pause in order to do it. Passive sentences play their own trick, often hiding who did the action, as in The Eiffel Tower was built in 1889, which never tells you by whom.
The sets cover both the everyday cases and the times when no article belongs at all, and spotting a missing or extra article in a finished sentence is harder than filling a blank, so those correct-or-incorrect items make a satisfying step up. Articles, agreement, and tense are exactly the small things that mark a sentence as natural or not, which is why a little focused practice goes a long way.
Because grammar like this appears in nearly every sentence, a little practice cleans up a lot of small errors quickly. Choose the rule you want to nail down and work through these free interactive English quizzes.

Tap any card!Articles and Determiners
When do you say "a," "an," "the," or nothing at all? English articles trip up learners at every level, and these quizzes give you steady, low-pressure practice with them.
Mastering English Articles and Determiners
Each quiz asks you to fill a blank with a, an, the, or no article, in sentences like New York is ___ interesting city and ___ Nile is the longest river in the world. A later set adds correct-or-incorrect items, where you read a finished sentence and decide whether an article is missing or out of place.
These quizzes run from beginner to intermediate and cover the everyday cases as well as the times when no article belongs at all. Spotting an extra or missing article in a complete sentence is harder than filling a gap, so the correct-or-incorrect items make a satisfying step up. Articles are small words, but using the wrong one, or dropping a needed one, is among the most common giveaways of a non-native sentence.
Did You Know?
The choice between a and an depends on sound, not spelling. That is why European takes a even though it begins with a vowel letter, since it actually starts with a "y" sound.
The rule works in the other direction too. A word like hour takes an because the h is silent and the word begins with a vowel sound, so your ear is the real guide here, not your eyes.
How the Quizzes Work
Each quiz is short, about five minutes, and you can repeat any of the 3 sets whenever you want the rules to feel automatic. Because articles appear in almost every sentence, a little practice quickly cleans up a lot of small errors, and reading your answer back aloud is a quick way to feel whether an article belongs.

Irregular English Verbs
Why does "go" become "went" while "hurt" never changes at all? Irregular English verbs follow their own rules, and these quizzes drill both the past tense and the past participle until they stick.
Practicing Irregular English Verbs
The quizzes work two ways. Some give you the base verb and ask for the form directly, with tricky ones like begin, ride, tear, break, fly, and throw. Others place the verb inside a full sentence, like Have you ever (meet) a Hollywood celebrity?, so you decide between the simple past and the participle based on the words around it.
These sets are pitched at an intermediate level. Reading the whole sentence matters, because the same verb can come out looking different depending on the context it sits in. Some quizzes ask only for the participle, while others want the simple past, so you practice both forms side by side.
Did You Know?
Some irregular verbs barely change at all. A word like hurt keeps the same spelling in its base, past, and participle forms, and overcome looks identical to its base, while others shift completely, like awake turning into awoken.
One verb stands apart from all the rest. The verb be has two different past forms depending on the subject, something none of the other verbs on the list do, so it is worth slowing down on.
How the Quizzes Work
Each quiz is short, about five minutes, and you can repeat any of the 6 sets until the forms come without hesitation. Watching for helping verbs like has and have, or time words like yesterday, makes the right choice much clearer, and grouping the verbs that change the same way makes the whole set easier to memorize.

Tenses
Past, present, or future, and which exact form? English verb tenses are where many learners stall, and these quizzes give you a thorough workout across all of them.
Working Through English Verb Tenses
Each quiz asks you to drop the right verb form into a gap, in sentences like All the workers ___ on the streets yesterday and Andy ___ a cake for tomorrow morning, with several correct-or-incorrect sentences mixed in to judge. The range grows across the sets, reaching the present perfect continuous and the used to form for past habits.
These quizzes run from beginner to intermediate and make a strong all-round check before you tackle trickier tense work. Each set leans on different combinations of past, present, and future, so you keep meeting the same tenses in fresh situations. The judging items are the sneaky ones, since a sentence can look fine until you test whether the time word and the verb tense actually agree.
Did You Know?
A sentence can fall apart on its time markers alone. Pairing a past action with a future time word, for example, simply cannot work, and spotting why is the kind of thing that sharpens your eye for tense.
Doubling up on the past is another common slip. Using two past markers at once, like an extra past form where one already does the job, is exactly the error these quizzes are built to catch.
How the Quizzes Work
Each quiz is short, about five minutes, and you can repeat any of the 4 sets whenever you want a tense to feel solid. Scanning for the time word first, then matching the verb to it, is a habit that pays off everywhere, and once you trust those markers even the perfect and continuous forms stop feeling slippery.

Verb Forms and Patterns
Is it "enjoy swimming" or "enjoy to swim"? Knowing when a verb takes the -ing form and when it takes to plus the base verb is a classic English puzzle, and this quiz makes it click.
English Verb Forms and Patterns
The quiz asks you to choose the right form in sentences like Brian doesn't mind ___ in the office until late at night and Erin and Erica plan ___ a European cruise next month, with a couple of correct-or-incorrect items at the end. Each sentence gives you the context you need to decide which pattern the main verb calls for.
It is pitched at an intermediate level, since these patterns are something you learn verb by verb rather than from a single rule. Working through real sentences is the fastest way to build a feel for which verbs go with which form. You will meet verbs that always take one form, verbs that always take the other, and the handful that allow both.
Did You Know?
A few verbs accept both forms but change meaning entirely. To stop doing something means you quit it, while to stop to do something means you pause in order to do it, so the form you choose changes what you are actually saying.
That is why memorizing a single rule does not work here. The pattern lives with each verb, which is exactly what makes targeted practice so useful.
How the Quizzes Work
The quiz is short, about five minutes, and you can repeat it whenever you want the patterns to feel natural. Seeing the verbs in full sentences, again and again, is what builds reliable instinct, and a few focused rounds is usually enough to start trusting your judgment on new verbs.

Verb Tenses and Structure
Who is doing the action, and how does a single word like "must" or "might" change a whole sentence? These quizzes cover active and passive voice and the English modal verbs.
English Voice and Modal Verbs
One quiz shows you full sentences like The car is washed on Mondays and Camille prepared the sandwiches this morning and asks whether each is active or passive. The other works on modal verbs such as can, must, might, and should, with the intended meaning marked in brackets so you can match the right one.
These sets run from beginner to intermediate. The voice quiz suits learners who know the basics and want to spot who is acting quickly, while the modal quiz is a friendly place to start if those small words still feel slippery. Telling active from passive trains you to find the real subject of a sentence, and the modal set sharpens how precisely you express ability, obligation, and possibility.
Did You Know?
Passive sentences often hide the doer. A line like The Eiffel Tower was built in 1889 never tells you who actually built it, which is one of the clearest signs that a sentence is in the passive voice, and it is also why formal and scientific writing leans on the passive so heavily.
Modal verbs pack a lot into a tiny word. Saying you can do something is very different from saying you might or you must, so swapping one modal for another completely changes the message.
How the Quizzes Work
Each quiz is short, about five minutes, and you can repeat both whenever you want the ideas to feel solid. The bracketed meaning clues make the modal set especially approachable, and switching between the two quizzes keeps both skills fresh at the same time. Ready to sharpen your grammar?
