Help the absent-minded wizard complete his secret potion recipe by dragging the correct words into the instructions.
First, slice three magical leaves from the enchanted forest tree.
Next, add a single glowing berry from the whispering bush.
Finally, stir the cauldron counter-clockwise and say the magic word to banish all evil witches from the kingdom.
First, slice three magical leaves from the enchanted forest tree.
For most nouns ending in "-f" or "-fe" (like leaf), we drop the "f" and add "-ves" to make them plural.
Next, add a single glowing berry from the whispering bush.
The phrase "a single" tells us we need the singular form, which is berry.
Finally, stir the cauldron counter-clockwise and say the magic word to banish all evil witches from the kingdom.
For nouns ending in an "ch", "sh", "s", "x", or "z" sound (like witch), we add "-es" to make them plural.
Noun
If you've ever frozen mid-sentence wondering whether to say an information or some information, child or children, they or them — you've hit the core of how English uses nouns. Nail this down and articles, plurals, possessives, and pronoun choice all stop feeling like guesswork.
A noun is a word that names something: a person, place, thing, idea, action, or quality. Nouns are the building blocks every other part of speech bolts onto. Spot one in a sentence and you can usually predict the article, the verb form, and the pronouns that follow.
Grammatical number
If you've ever written The data shows and been told it should be The data show — or written The list of items are when it should be is — you've hit a grammatical-number trap. Number agreement looks simple in theory (one takes singular, more than one takes plural) but English has enough irregular plurals and tricky collective nouns to keep you on your toes.
Grammatical number is the singular/plural distinction on nouns, pronouns, and verbs. Most English nouns form plurals with -(e)s; pronouns have irregular pairs (I/we, he/they); verbs agree with their subject (He goes vs They go).
English grammar
If you can speak English but feel you're forever guessing — should that be a/the?, would have been or had been?, who or whom? — you don't have a vocabulary problem; you have a grammar problem. Grammar is the system that turns isolated words into precise meaning, and the only difference between guessing and knowing is studying it deliberately.
English grammar is the system of rules that govern how meanings are encoded in English: word formation, phrase and sentence structure, tenses, agreement, word order, and punctuation.
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.
