The correct collocation is "Limited budget," which means that there is a restricted amount of money available for spending or investment.
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.
Vocabulary
Vocabulary vs grammar: grammar is the system of rules for combining words. Vocabulary is the stock of words themselves. You can have perfect grammar and still sound limited if your word stock is narrow (good instead of outstanding/remarkable/decent). Most fluency-feel above B1 comes from vocabulary breadth, not grammar complexity.
Vocabulary = word-focused learning: words, collocations, phrasal verbs, idioms, across CEFR A1–C2.
Diagnostic: can you express the idea but it sounds "flat" or overly simple? → vocabulary issue. Can't construct the sentence at all? → grammar issue.
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, A1–A2. Medium = one rule but realistic distractors, A2–B1. 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.
