Basics: Past Simple - Irregular Verbs
While most English verbs form the past tense by adding "-ed," irregular verbs follow entirely different patterns. For example, the past simple of buy is bought, and catch becomes caught. Memorizing these unique forms is essential for accurately talking about completed actions in the past.
This challenge tests your ability to identify and use the correct past tense forms of common irregular verbs like teach, choose, and catch. You will practice applying these verbs in a variety of engaging contexts, from everyday situations like shopping, cooking, and camping, to imaginative scenarios like a disastrous dinner, a wizard's morning routine, and a dog's funny confession.
You'll work through 15 questions in single-choice, multi-choice, drop-down, and drag-and-drop formats.

Complete the hero's slightly exaggerated retelling of the incident with the correct word.

Finish the text message to a sympathetic friend by selecting the correct verb form.
"I completely ruined the mood on my date last night. I ___ a documentary about insects instead of a romantic comedy."
The correct answer is chose.
The verb "choose" is irregular. Its past simple form is "chose" (spelled with only one 'o'). "Chosen" is the past participle, which would need a helper verb like "had" or "have."
The correct answers are hid, left, and put.
All three of these are correctly formed irregular verbs that make sense in the sentence!
- hide becomes hid (not hided)
- leave becomes left (not leaved)
- put stays exactly the same in the past tense: put (never putted!)

The past simple form of "buy" is "bought." It is an irregular verb, so "buyed" is incorrect.

The past simple form of "lose" is "lost." It is an irregular verb, so we do not add "-ed".
The correct answers are The chef caught the kitchen towel on fire. and I ate three slices of bread while waiting.
Irregular verbs do not follow the standard "-ed" rule for the past tense.
- catch becomes caught
- eat becomes ate
- bring becomes brought (not bringed)

Past tense
If you've ever told a story in English and felt the timeline get tangled — I came home, the dog ate, the cat slept — you've hit the limits of using simple past for everything. The past tense system has four forms specifically because real stories have layered timing: things that happened before other things, actions caught in progress, sequences of completed events.
The past tense has four English forms: simple past (I walked), past progressive (I was walking), past perfect (I had walked — earlier than another past event), past perfect progressive (I had been walking — ongoing up to a past point). Plus irregular verbs for the simple-past form.
Simple tense
If you're at A1/A2 and the array of English tenses feels overwhelming, here's the good news: most of what you need to say at the start fits in the simple forms. I work, I worked, I will work — three forms cover habits, completed past actions, and basic future. Master these first; the progressive and perfect come more easily once the simple is solid.
The simple aspect is the unmarked verb form — no progressive -ing, no have + past participle. I go, I went, I will go. Marks single completed actions, habits, or permanent states.
Irregular verb
If you've ever said I goed or I taked and felt the sentence collapse — you've hit irregular verbs head-on. The 200 most-used English verbs include nearly every irregular one, so there's no clever shortcut: you memorise them, drill them, and let them become automatic. The good news is that once they're automatic, half your past-tense problems disappear.
An irregular verb doesn't follow the -ed past-tense pattern. Instead its past tense and past participle change shape: go → went → gone, eat → ate → eaten, take → took → taken, put → put → put. About 200 verbs in common use; most of them are also the most frequent verbs in English.
Morphology
If you've ever encountered a word like unmistakable or misinterpretation and worked out its meaning from the pieces (un- + mistake + -able; mis- + interpret + -ation) — you've used morphology. The system isn't unique to English, but English's mix of Germanic and Latin roots gives it more building blocks than most. Knowing the common ones triples your effective vocabulary.
Morphology is the study of how words are built from smaller parts: roots, stems, prefixes (un-, re-, pre-, mis-), and suffixes (-tion, -able, -ly, -ness). Recognising these pieces lets you decode unfamiliar words instead of memorising them whole.
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.
A1 | Elementary | Beginners
If you can say your name, ask Where is the toilet?, and read a simple bus sign — but freeze when someone speaks at normal speed — you're at A1. That's not a problem to fix; it's the level where most learners actually live for a while, and recognising it lets you pick the right material instead of drowning in advanced grammar that wasn't meant for you yet.
A1 is the starting level of the CEFR framework, covering basic everyday communication: greetings, introductions, simple personal questions, present-tense forms of be/have/do, and core determiners and prepositions.
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.
