My roommate wakes up at 6:00 AM every single day, but he doesn't make coffee for me. Instead, he just drinks a loud, fizzy energy drink and runs out the door!
Use the base verb + s for the third-person singular (he, she, it) in affirmative sentences: "he wakes", "he drinks".
To form a negative sentence in the Present Simple for "he", use doesn't (does not) + the base verb.
Present tense
- I work here. — simple present (habit/permanent)
- I am working now. — present progressive (happening right now)
- I have lived here for 10 years. — present perfect (started past, still true)
- I have been waiting for an hour. — present perfect progressive (duration up to now)
Four present tense forms: simple (habits/facts), progressive (now/temporary), perfect (past → present relevance), perfect progressive (ongoing duration). Each encodes a different relationship between the action and the present moment.
Trap: "I am living here for 10 years" ❌ — started in the past + still true = present PERFECT (have lived/have been living), not progressive.
Simple tense
- ✅ I go to work every day. — present simple (habit)
- ✅ She went home yesterday. — past simple (completed action)
- ✅ I will call you later. — future simple (promise/decision)
- ✅ Water boils at 100°C. — present simple (general truth)
The simple aspect is the default, unmarked verb form. Present simple = habits, facts, schedules. Past simple = completed actions. Future simple = predictions, promises, decisions. No auxiliary needed (except will for future and do for questions/negatives).
Rule: if the action is a fact, habit, completed event, or scheduled future — and you don't need to emphasise it being in-progress or connected to now → simple tense.
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.
Habits and Routines
- ✅ I always get up at 7. — ❌ I get up always at 7. (adverb before main verb)
- ✅ She usually walks to work. — present simple for current habit
- ✅ I used to smoke. — past habit (no longer true)
- ✅ He would always bring flowers. — would for repeated past actions
Habits and routines use present simple + frequency adverbs for current habits, and used to / would for past habits. Adverb placement: before the main verb, after be.
Rule: frequency adverbs (always, usually, often, sometimes, never) go BEFORE the main verb but AFTER be: She always eats breakfast vs She is always hungry.
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.
A1 | Elementary | Beginners
- ✅ My name is Anna. — present simple of be
- ✅ Where is the station? — basic *wh-*question
- ✅ I have two brothers. — possession with have
- ✅ She likes coffee. — third-person -s
These are A1 sentences — the starting level of the CEFR framework. At A1 you can introduce yourself, ask and answer simple personal questions, and handle basic everyday transactions using present tense, be/have/do, and core vocabulary.
If you can say these but freeze at normal speaking speed, you're solidly A1 — and that's exactly where to start.
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.
