Quick answer: Beginners only need about a dozen grammar rules at first: subject-verb-object order, a subject in every sentence, -s with he/she/it, am/is/are, three simple tenses, common irregular verbs, do/does/did for questions and negatives, a/an/the, plurals, adjective position and in/on/at. Master these before moving to advanced tenses.↗ Share on X

If you are just starting English, you do not need hundreds of grammar rules. You need about a dozen, used every day, in almost every sentence you will say or write. Learn the word order (subject, verb, object), how verbs change with "he, she, it," the three simple tenses, how to ask questions and say "no," and when to use "a," "an," and "the." Those rules cover most of what beginners get wrong. Everything else can wait until these feel automatic.

This article gives you those rules in the order that makes sense, with short examples and the mistakes teachers see most often.

Why start with a small set of rules?

Grammar books are long because they try to cover every case. A beginner does not meet every case. You meet the same few patterns again and again: "I work," "She works," "Do you work?", "I don't work," "I worked yesterday."

If those patterns are solid, people understand you even when your vocabulary is small. If they are shaky, people get confused even when you know many words.

So the goal is not to "know grammar." The goal is to make a few rules so automatic that you stop thinking about them.

The 12 rules to learn first

Here they are, in the order most teachers introduce them.

1. Keep the word order: subject, verb, object

English is strict about order. The person or thing doing the action comes first, then the action, then what receives it.

• Correct: Maria reads books.
• Wrong: *Reads Maria books.* / *Maria books reads.*

Many languages let you move words around. English mostly does not. When in doubt, go back to subject, verb, object.

2. Every sentence needs a subject

In Spanish or Portuguese you can say "Is raining" with no subject. In English you must add one, even if it means nothing.

• Correct: It is raining. / It is late.
• Wrong: *Is raining.* / *Is late.*

The little word "it" (or "there") fills that empty spot.

3. Add -s to the verb with he, she, and it

In the present tense, the verb changes only for one person or thing that is not "I" or "you."

• She works at a bank.
• My brother lives in Texas.

This is the single most common beginner mistake. Say the sentence out loud and listen for the "s."

4. Use "be" correctly: am, is, are

"Be" is irregular, so memorize it as a block:

• I am
• you / we / they are
• he / she / it is

Also remember that English uses "be" for age and some feelings where other languages use "have":

• Correct: I am 30 years old. / I am hungry.
• Wrong: *I have 30 years.* / *I have hunger.*

5. Learn three tenses first: past, present, future

You can say a lot with just these three simple forms.

Add the present continuous ("I am working now") for things happening right now. Leave the perfect tenses ("have worked") for later.

6. Memorize the most common irregular past verbs

Many everyday verbs do not use -ed in the past. Learn these first, because you will use them constantly:

• go → went
• have → had
• do → did
• make → made
• get → got
• see → saw
• say → said
• come → came
• take → took
• know → knew

Write them on a card. Test yourself for five minutes a day until they come out without thinking.

7. Use "do" and "does" to ask questions

In the present and past simple, you usually need a helper word to make a question.

• Do you like coffee?
• Does she live here? (not *Does she lives here?*)
• Did they call you?

Notice: once "does" or "did" appears, the main verb goes back to its base form. The -s or -ed moves to the helper.

8. Use "don't," "doesn't," and "didn't" to say no

Same idea for negative sentences.

• I don't eat meat.
• He doesn't drive. (not *He doesn't drives.*)
• We didn't go.

With "be," you just add "not": I am not tired. She isn't here.

9. Pick "a," "an," or "the"

This one takes time, but the basic rule is simple:

• a / an = one thing, and the listener does not know which one yet. "I bought a car."
• the = a specific thing both of you know. "The car is red."
• an goes before a vowel *sound*: an apple, an hour (the "h" is silent), but a university (it starts with a "you" sound).

Plural nouns in general need no article: "Dogs are loyal," not *"The dogs are loyal"* when you mean all dogs.

10. Make most plurals with -s

• one book → two books
• one box → two boxes (after s, x, ch, sh)
• one city → two cities

A few common ones are irregular: man → men, woman → women, child → children, person → people, foot → feet, tooth → teeth.

11. Put adjectives before the noun

In many languages the describing word comes after. In English it comes before, and it never takes an -s.

• Correct: a red car, two big houses
• Wrong: *a car red*, *two bigs houses*

12. Use in, on, and at for time and place

Prepositions are hard in every language. For beginners, this simple table handles most cases:

These show up in almost every beginner's writing. Check your own sentences for them.

1. Missing -s: *She work here.* → She works here.

2. Double past: *Did you went?* → Did you go?

3. "Have" for age: *I have 25 years.* → I am 25 years old.

4. No subject: *Is very cold today.* → It is very cold today.

5. Wrong question order: *You are ready?* → Are you ready? (Spoken English sometimes uses the first form, but in writing use the second.)

6. "People is": *People is nice.* → People are nice. "People" is always plural.

7. "Explain me": *Can you explain me?* → Can you explain it to me?

8. "Informations," "advices": these words have no plural in English. Say "some information," "a piece of advice."

How do you practice so the rules stick?

Reading a rule once does almost nothing. What works is short, repeated use. Here is a simple weekly routine for a beginner with 15 to 20 minutes a day:

Next week, pick 2 new rules and keep reviewing the old ones.

A few extra tips that help:

• Write about yourself. "I wake up at 6. I drink coffee. My wife works at a school." Personal sentences are easier to remember than textbook ones.
• Fix one mistake type at a time. If you try to fix everything at once, you fix nothing.
• Say it before you write it. If a sentence sounds strange when you say it out loud, look at the verb first.
• Keep a mistake notebook. Each time someone corrects you, write the wrong and the right version side by side.

What can you safely leave for later?

It is easy to get lost in advanced topics too early. You can wait on these until the 12 rules above feel natural:

• Perfect tenses (have done, had done, will have done)
• Passive voice (the house was built)
• Conditionals beyond the simple "if" (If I had known...)
• Reported speech (She said that she was tired)
• Phrasal verbs in large numbers (put up with, get over)

You will meet these in real texts, and that is fine. Understand them when you read them. Do not try to produce them yet.

How do you know you are ready to move on?

A good sign is when you can write a short paragraph about your day, check it, and find no errors from the 12 rules above. Another sign: you notice mistakes in other people's English, or in your own speech, right after you say them.

When that happens, move to the present perfect ("I have lived here for two years"). It is the next tense most learners need, and it is the one that causes the most confusion.

Your next step today

Take a piece of paper and write 10 sentences about yesterday. Use at least 5 of the irregular verbs from rule 6. Then check each sentence against three things only: the subject is there, the verb is in the past, and questions or negatives use "did." Fix what you find, read the corrected version out loud twice, and save it. Tomorrow, do the same about today, in the present tense.

FAQ

How many grammar rules does a beginner need to learn?

About a dozen core rules cover most everyday sentences: word order, subjects, verb -s, the verb be, three simple tenses, irregular past verbs, questions, negatives, articles, plurals, adjective position and basic prepositions.

What is the most common English grammar mistake for beginners?

Forgetting the -s on the verb with he, she and it in the present tense, as in 'She work here' instead of 'She works here.'

Should beginners study the present perfect right away?

No. Get comfortable with the simple past, present and future first. The present perfect is a good next step once you can write a short paragraph without basic errors.
