To ChallengesPreviousNext

Verb

Verb vs noun vs adjective: nouns name things. Adjectives describe. Verbs express what happens or what IS. The test: can it take tense (walked, will walk)? Can it take -ing? Can it follow to as an infinitive (to walk)? Yes to any → verb. English often converts freely between classes (run = noun or verb), so context decides.

A verb = action/state/occurrence word. 5 forms (base, -s, past, past participle, -ing). Carries tense, aspect, mood, voice. The one required element in every sentence.

Diagnostic: does it change for tense (walk → walked)? Can you put to before it (to walk)? Does it take -ing (walking)? → verb.

Phrasal verb

Phrasal verb vs verb + preposition: a phrasal verb has a non-literal combined meaning (run into = meet by chance). A verb + preposition keeps its literal meaning (run into the room = physically run inside). The test: is the meaning predictable from the parts? No → phrasal verb. Yes → just a verb followed by a preposition.

Phrasal verbs combine verbs with particles/prepositions to create new meanings. They're the single biggest gap between textbook English and real native usage.

Diagnostic: can you guess the meaning from the individual words? No → phrasal verb (learn as unit). Yes → literal verb + preposition.

Collocations

Collocation vs idiom: both are fixed expressions, but collocations are transparent (you can guess the meaning from the words: heavy rain = a lot of rain), while idioms are opaque (kick the bucket ≠ literally kick anything). Collocations are about which words pair naturally; idioms are about hidden meaning.

Collocations are habitual word combinations: make a decision, strong coffee, take a shower. Grammar allows alternatives, but fluency demands the conventional pairing.

Diagnostic: if the meaning is clear but the combination sounds "off" to native ears (do a mistake instead of make a mistake) — it's a collocation issue.

Vocabulary for B1/Intermediate

B1 vs B2 vocabulary: B1 lets you express opinions and discuss abstract topics. B2 adds precision — choosing between big/large/substantial/considerable based on register and context. The jump is from "I can say it" to "I can say it the RIGHT way for this audience."

B1 vocabulary = ~2,500–4,000 words. Abstract topics, opinions, news, refined emotions, discourse markers, expanded phrasal verbs.

Diagnostic: can you discuss news and give opinions? Yes → B1. Do you find yourself reaching for a more precise word and settling for a vague one? → need B2.

B1 | Intermediate

B1 vs B2: B1 handles standard everyday communication and simple opinions. B2 handles abstract topics, sustained arguments, and nuanced register. If you can chat about your life but struggle to debate an issue or write a formal essay, you're B1.

B1 is the intermediate CEFR level: independent handling of familiar topics, second conditional, basic passive, reported speech, and linking words for cause and contrast.

Diagnostic: can you read a newspaper article on a familiar topic and summarise the argument? Comfortably → B2. Struggle with abstractions → still B1.

Easy

Easy vs Medium vs Hard: Easy = one rule, obvious answer, A1A2. Medium = one rule but realistic distractors, A2B1. Hard = interacting rules, edge cases, B2+. Start Easy to check you have the basics before moving up.

The Easy tag filters for single-rule, short-sentence, common-vocabulary challenges designed for beginners or for anyone wanting a confidence check on fundamentals.

Diagnostic: if you get Easy questions wrong, stay here — your foundations need work. If they feel trivial, move to Medium.
