The correct answers are He walked too loudly to scare anyone. and He wasn't quiet enough to be a good ghost.
We often use too + adjective/adverb + to-infinitive to show a negative result (e.g., too loudly to scare).
We use adjective/adverb + enough + to-infinitive to show ability or sufficiency (e.g., quiet enough to be).
"He moved enough quickly" is incorrect because enough must follow the adverb (it should be quickly enough). "He was too much transparent" is incorrect because we only use too before adjectives, not too much (it should be too transparent).
Adverb
- ✅ She sings beautifully — ❌ She sings beautiful
- ✅ He drives carefully — ❌ He drives careful
- ✅ They arrived late — ✅ a late train (same form, both roles)
- ✅ She works hard — ❌ She works hardly (different meaning!)
The -ly words are adverbs — they modify verbs, adjectives, or other adverbs, telling you how, when, where, or to what degree.
Pattern: most adjectives become adverbs by adding -ly, but watch the exceptions — fast, hard, late, well — that keep the same shape or change meaning entirely.
Adjective
- ✅ a tall building — ❌ a tally building
- ✅ The soup is hot — ❌ The soup is hotly
- ✅ a lovely small old table — ❌ a small lovely old table
- ✅ She seems tired — ❌ She seems tiredly
These bolded words are adjectives — words that describe nouns or pronouns. They sit before a noun (a tall building) or after a linking verb (The soup is hot).
Pattern: if a word can slot between a/the and a noun (a ___ thing) and can take -er/-est, it's almost certainly an adjective.
Infinitive
- ✅ I want to go. — to-infinitive after want
- ✅ She can swim. — bare infinitive after modal
- ✅ Let me help. — bare infinitive after let
- ❌ I enjoy to read. — wrong (enjoy takes gerund, not infinitive)
The infinitive has two forms: to-infinitive (to go) after verbs like want, decide, plan, hope; bare infinitive (go) after modals and causatives (let, make, help).
Rule: after want, need, decide, plan, hope, expect, agree, refuse → to-infinitive. After can, will, must, let, make → bare infinitive. After enjoy, avoid, finish → gerund, NOT infinitive.
Word order
- ✅ She (S) eats (V) cake (O). — standard SVO
- ❌ Cake eats she. — SOV (not English)
- ✅ a lovely little old rectangular green French silver whittling knife — adjective order (opinion→size→age→shape→colour→origin→material→purpose)
- ✅ Never have I seen… — inversion after negative adverb
English word order = SVO (subject-verb-object) as default. Adjectives follow a fixed sequence (opinion→size→age→shape→colour→origin→material). Adverb placement varies by type. Deviations signal questions, emphasis, or literary style.
Rule: when in doubt, default to SVO. English position = meaning. Move a word and you change the grammar or the emphasis.
Negation
- ✅ I don't see anything. — ❌ I don't see nothing. (double negative in standard English)
- ✅ She never goes out. — never already negates (no doesn't needed)
- ✅ He doesn't like coffee. — do-support for negation
- ✅ Nobody came. — negative subject (no auxiliary needed)
Negation uses not after an auxiliary/modal, or do-support when there's no auxiliary. One negative per clause in standard English — never, nobody, nothing already negate without adding not.
Rule: one negative element per clause. I don't see anything or I see nothing — never both together in standard English.
A2 | Elementary | Pre-intermediate
- ✅ I went to the cinema yesterday. — past simple
- ✅ I have visited Paris twice. — present perfect (life experience)
- ✅ If it rains, I'll take an umbrella. — first conditional
- ✅ You should see a doctor. — modal for advice
These patterns are A2 — the second CEFR level. At A2 you move past survival phrases into real grammar: past tenses, the present perfect, basic conditionals, and modals for advice/obligation.
Marker: if you can describe yesterday and give simple advice, but struggle with abstractions or nuance, you're at A2.
Medium
- If I were you, I would apologise. — one rule (second conditional), but distractors like was tempt you
- Answers require active thought, not instant pattern recognition
- Vocabulary and context are realistic, not artificially simplified
- Usually tests one rule, but the wrong answers are plausible
Medium marks middle-difficulty challenges: A2–B1, one rule tested, but with realistic distractors that require genuine understanding.
Use "Medium" when Easy feels too obvious but Hard feels overwhelming. This is where most productive learning happens — the sweet spot of difficulty.
