Transitive and intransitive verb

  • She broke the vase. — transitive (needs object)
  • Rivers flow. — intransitive (no object possible)
  • She arrived the airport.arrive is intransitive (arrived at)
  • The vase broke. / She broke the vase. — ambitransitive

Transitive verbs need a direct object; intransitive verbs can't take one; ambitransitive verbs work both ways. Many errors come from treating intransitive verbs as transitive (explain me ❌) or vice versa.

Rule: can you ask "[verb] WHAT/WHOM?" and get an answer? Yes → transitive. No answer possible → intransitive. Works with or without? → ambitransitive.

Verb

  • walk → walk / walks / walked / walked / walking (5 forms, regular)
  • go → go / goes / went / gone / going (5 forms, irregular)
  • be → am/is/are/was/were/be/being/been (8 forms)
  • can → can / could (modal: only 2 forms, no -s, no -ing)

A verb is the one word class every English sentence requires. Carries tense (when), aspect (duration), mood (attitude), and voice (active/passive). Regular verbs add -ed; ~200 irregular verbs have unpredictable past forms.

Key insight: fix your verbs and most grammar problems disappear. Wrong tense, wrong agreement, wrong form — verb errors account for the majority of grammatical mistakes.

Object

  • Sam fed the dogs. — direct object (what was fed)
  • She sent him a present. — indirect object (who received it)
  • She waited for Lucy. — prepositional object (after preposition)
  • I gave her a book. — indirect + direct object together

An object is what a verb acts on or directs its action toward. Direct = the thing affected. Indirect = the recipient. Prepositional = after a preposition.

Test: Verb + what/whom? = direct object. Verb + to/for whom? = indirect object. After a preposition? = prepositional object.

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: A2B1, 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.
