English grammar for beginners comes down to a small set of rules you use in almost every sentence: put words in the order subject + verb + object, make the verb match the subject, pick the right tense, use "a," "an," and "the" correctly, and end each sentence with the right punctuation. Learn the 12 rules below, practice them with short sentences every day, and most of the mistakes people notice in your English will disappear.
You do not need a thick grammar book. What makes English sound wrong is a handful of basic errors repeated often. Fix those first.

I Am Bored vs I Am Boring: The Grammar Fix →English is strict about word order. The normal pattern is:
Subject + Verb + Object
- *Maria* (subject) *drinks* (verb) *coffee* (object).
- *The dog* (subject) *found* (verb) *the ball* (object).
The subject is who or what does the action. The verb is the action. The object is what receives the action.
If you change the order, the meaning changes. "Coffee drinks Maria" means the coffee is drinking Maria.
When you add a place and a time, the usual order is: who – does – what – where – when.
- *I met my friend at the park yesterday.*
A common beginner mistake is putting the time in the middle: "I yesterday met my friend." Put time at the start or the end, not between the subject and the verb.

The 12 grammar rules that fix most beginner mistakes
Here is the short list. Each rule is explained in more detail below.
1. Every sentence needs a subject and a verb.
2. The verb must agree with the subject (he works, they work).
3. Add -s to the verb for he, she, and it in the present simple.
4. Use a before consonant sounds and an before vowel sounds.
5. Use the when the listener knows which thing you mean.
6. Adjectives go before the noun (a red car, not a car red).
7. Use do/does to make questions and negatives in the present simple.
8. Use did for questions and negatives in the past, and keep the main verb in its base form.
9. Most plural nouns add -s or -es.
10. Use the right pronoun: I/me, he/him, she/her, we/us, they/them.
11. Start every sentence with a capital letter, and always write "I" as a capital.
12. End statements with a period and questions with a question mark.
Why does "he work" sound wrong? (Subject-verb agreement)

Gerunds vs Infinitives: 'Stop Eating' or 'Stop to Eat'? →In the present simple tense, English adds -s to the verb when the subject is he, she, it, or one person or thing.
| Subject | Verb "to work" | Verb "to have" | Verb "to be" |
|---|---|---|---|
| I | work | have | am |
| You | work | have | are |
| He / She / It | works | has | is |
| We | work | have | are |
| They | work | have | are |
Examples:
- *She works at a bank.* (not "She work")
- *My brother has two kids.* (not "My brother have")
- *The store opens at 9.* (one store, so "opens")
A quick trick: if you can replace the subject with "he," "she," or "it," the verb needs the -s.
Watch out for spelling:
- Verbs ending in -s, -sh, -ch, -x, -o add -es: watch → watches, go → goes.
- Verbs ending in consonant + y change to -ies: study → studies.
When do you use "a," "an," and "the"?
These small words are called articles.
Use "a" or "an" for one thing that is not specific yet.
- *I want a sandwich.* (any sandwich)
- *She is an engineer.*
"A" or "an" depends on the sound, not the letter.
- a before a consonant sound: a book, a car, a university (sounds like "you")
- an before a vowel sound: an apple, an egg, an hour (the "h" is silent)
Use "the" when both people know which thing you mean.
- *I bought a shirt. The shirt is blue.* (first time "a," second time "the")
- *Close the door.* (the door in this room)
- *The sun is hot.* (there is only one)
Use no article for general ideas and plural things in general.
- *I like music.* (not "I like the music," unless you mean specific music)
- *Dogs are loyal.* (dogs in general)
How do you pick the right tense?
A tense tells when something happens. Beginners can do a lot with just four.
| Tense | When to use it | Example |
|---|---|---|
| Present simple | Habits, facts, schedules | I drink tea every morning. |
| Present continuous | Happening right now | I am drinking tea now. |
| Past simple | Finished action in the past | I drank tea yesterday. |
| Future with "will" | Decisions, predictions | I will drink tea later. |
Do not use "-ing" for habits. Say "I go to the gym every day," not "I am going to the gym every day."
Irregular past verbs do not add -ed. You have to learn them one by one. Start with the most common:
go → went, have → had, make → made, get → got, see → saw, say → said, take → took, come → came, know → knew, think → thought.
Learn five a week. By the end of the month, you will know the 20 you use most.
How do you make questions and negatives?
In the present simple, you need a helper verb: do or does.
Questions:
- *Do you like pizza?*
- *Does she speak Spanish?* (not "Does she speaks")
Negatives:
- *I don't like pizza.*
- *He doesn't work on Sundays.* (not "He doesn't works")
Notice: when you use does or doesn't, the -s moves to the helper. The main verb goes back to its basic form.
In the past, the helper is did for everyone:
- *Did you call him?*
- *I didn't see the message.* (not "I didn't saw")
The verb "to be" is different. It does not need a helper:
- *Are you tired?* / *She isn't here.* / *Was it expensive?*
Where do adjectives go?
In English, the adjective (the describing word) goes before the noun.
- *a big house* (not "a house big")
- *an old red truck*
After verbs like be, look, seem, feel, the adjective comes after:
- *The house is big.*
- *You look tired.*
Adjectives never take a plural form: "two big houses," not "two bigs houses."
Which pronoun is correct: "me" or "I"?
Use the subject pronoun before the verb and the object pronoun after it.
| Before the verb (subject) | After the verb (object) | Shows ownership |
|---|---|---|
| I | me | my |
| you | you | your |
| he | him | his |
| she | her | her |
| it | it | its |
| we | us | our |
| they | them | their |
- *She called me.* (not "She called I")
- *My friend and I went out.*
Quick test for "and I" or "and me": remove the other person. "Me went out" sounds wrong, so it is "My friend and I went out." "She invited I" sounds wrong, so it is "She invited my friend and me."
Also, its (no apostrophe) shows ownership: *The dog wagged its tail.* It's means "it is": *It's cold today.*
What are the easy punctuation rules to know first?
You do not need every comma rule on day one. Start with these:
1. Capital letter at the start of every sentence, for names (Maria, Texas, Monday, July), and for the word "I."
2. Period (.) at the end of a statement.
3. Question mark (?) at the end of a direct question.
4. Comma (,) in lists: *I bought eggs, milk, and bread.*
5. Apostrophe (') for short forms: don't, can't, I'm, it's.
Days of the week and months are capitalized in English: *Monday, January.* Many other languages write them in lowercase, so this is a frequent slip.
What common mistakes should you check first?
Before you send an email or a message, scan it for these five errors.
| Mistake | Wrong | Right |
|---|---|---|
| Missing -s | She like coffee. | She likes coffee. |
| Double past | I didn't went. | I didn't go. |
| Missing article | I am teacher. | I am a teacher. |
| Wrong word order | I yesterday called him. | I called him yesterday. |
| "Have" for age | I have 25 years. | I am 25 years old. |
The last one is common for speakers of Spanish, Portuguese, French, and Italian. In English, you are an age. You do not have it.
How do you practice so the rules stick?
Reading rules is not enough. You need to use them. Here is a simple 15-minute daily routine:
1. Minutes 1–5: Write five sentences about your day. Use the past simple. Example: *I woke up at 7. I ate eggs.*
2. Minutes 6–8: Check each sentence against the 12 rules above. Circle every verb and check the ending.
3. Minutes 9–12: Read your sentences out loud. Your ear will start to catch errors your eyes miss.
4. Minutes 13–15: Pick one rule you broke today. Write three new sentences that use it correctly.
Keep a small notebook of your own mistakes. After two weeks, the same two or three errors will keep showing up. Focus on those.
Your next step today
Take a piece of paper and write five sentences about yesterday. Then check them against just three rules: the -s for he/she/it, did + base verb for past negatives, and a/an before jobs ("I am a nurse"). Fix what you find. Tomorrow, add three more rules from the list. In four days you will have worked through all 12, using your own sentences instead of textbook examples.
FAQ
What are the most important English grammar rules for beginners?
Start with word order (subject + verb + object), subject-verb agreement (she works, not she work), articles (a, an, the), the four basic tenses, and using do/does/did for questions and negatives.
Should I say 'a university' or 'an university'?
Say 'a university.' The choice depends on the sound, not the letter. 'University' starts with a 'you' sound, which is a consonant sound, so it takes 'a.'
Why is 'I didn't went' wrong?
When you use 'did' or 'didn't,' the past tense is already shown by the helper verb. The main verb goes back to its base form: 'I didn't go.'
How long does it take to learn basic English grammar?
It depends on how often you practice. Working through a few rules a day with your own sentences, most beginners can cover the basics in a few weeks, then keep improving by fixing their own repeated mistakes.
