Modal verb

  • She can swim. — ❌ She can to swim. (modal + bare infinitive, no to)
  • You must leave now. — strong obligation
  • It might rain. — possibility (~50%)
  • He should apologise. — advice/recommendation

Modal verbs (can, could, may, might, must, shall, should, will, would) are auxiliaries expressing ability, permission, possibility, obligation, or speculation. Always + bare infinitive. Never inflected (she can, not she cans).

Rule: modals never take to after them, never add -s for third person, and can't combine directly (must can ❌ — use must be able to).

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.

English grammar

  • She is reading. — tense + aspect (present progressive)
  • The cat sat on the mat. — word order + articles
  • He gave her a book. — case + sentence structure
  • Does she know? — auxiliary for question formation

Every one of these involves English grammar — the rule system that turns words into precise meaning. It covers parts of speech, sentence structure, tenses, agreement, word order, and punctuation.

Grammar isn't about memorising rules — it's about understanding why one word order works and another doesn't.

Humor

  • "I before E, except after C" — weird, right? — playful self-contradiction
  • Grammar joke: A panda eats, shoots, and leaves. — comma changes everything
  • Silly contexts make rules memorable: the sillier the sentence, the harder it is to forget
  • Entertainment is a learning strategy, not a distraction

Humor marks practice material that's deliberately entertaining. The grammar is real; the packaging is playful. Designed to boost engagement and make rules stick through association.

Why it works: memory anchors to emotion. A funny example of comma misuse is remembered longer than a dry rule statement.

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.

Easy

  • She is a teacher. — one verb form, one rule
  • I have two cats. — basic possession, short sentence
  • He doesn't like coffee. — simple negation with do-support
  • Only one answer is clearly correct; distractors are obviously wrong.

Easy marks beginner-level challenges: A1–early A2, one rule at a time, everyday vocabulary, no trick questions.

Use "Easy" when you want to build confidence on a specific rule without interference from other grammar or tricky contexts.
