2. Basic Sentence Structure
Subject + Verb + Object (SVO)
The most common English sentence pattern:
3. Verb Tenses
| Tense | Use | Example |
|---|---|---|
| Present Simple | Habits, facts, general truths | I work every day. |
| Past Simple | Completed actions in the past | I worked yesterday. |
| Future Simple | Predictions, plans | I will work tomorrow. |
| Present Continuous | Actions happening now | I am working now. |
| Present Perfect | Past actions with present results | I have worked here for 5 years. |
4. Articles: a, an, the
a / an
Indefinite articles. one of many
a before consonant sounds:
a cat, a book, a university
an before vowel sounds:
an apple, an hour, an idea
the
Definite article. specific thing we both know
the + singular noun when there's only one:
the sun, the Earth, the President
the + noun when both speaker and listener know what we're referring to:
"Where is the bathroom?"
💡 Quick Tip
The sound matters, not the letter! We say "a university" (yu-), so it's "a university" not "an university." We say "an hour" (our-), so it's "an hour" not "a hour."
5. Common Mistakes to Avoid
❌ Their vs There vs They're
Their = possessive (their house), There = place (over there), They're = they are
Correct: They're going to their house over there.
❌ Your vs You're
Your = possessive (your book), You're = you are
Correct: You're going to love your new book.
❌ Its vs It's
Its = possessive (the cat licked its paw), It's = it is or it has
Correct: It's a beautiful day, and the dog is enjoying its walk.
❌ Subject-Verb Agreement
Singular subjects need singular verbs, plural subjects need plural verbs.
Correct: He likes coffee. They like coffee.
