If you're learning English grammar, you don't need to memorize a 400-page book. About ten rules cover most of the mistakes beginners make every day: making the verb match the subject, using "a," "an," and "the," knowing when to say "few" or "a few," picking the right tense, and putting words in the right order. Learn them one at a time, in the order below, and practice each one with short sentences about your own life.

Each step below gives you the rule in plain words, a wrong-and-right example, and a two-minute practice task.

Step 1: Does your verb match your subject?

This is the most common mistake in everyday English. In the present tense, when the subject is he, she, it, or one person or thing, the verb usually gets an -s.

• Wrong: *She work at a hospital.*
• Right: *She works at a hospital.*
• Wrong: *My brother don't like coffee.*
• Right: *My brother doesn't like coffee.*

With I, you, we, they, there's no -s: *They work. We don't like coffee.*

Watch out: words like *everyone, nobody, each* are singular. *Everyone is here*, not *everyone are here*.

Practice: write five sentences about a family member using *he* or *she*. Check every verb for the -s.

Step 2: When do you use "a," "an," and "the"?

These little words are called articles. Many languages don't have them, so they feel strange at first.

1. Use a or an for one thing that's new or not specific: *I bought a car.*

2. Use the when both people know which one you mean: *The car is red.* (We already talked about it.)

3. Use an before a vowel *sound*, not just a vowel letter: *an hour* (the "h" is silent), but *a university* (it starts with a "you" sound).

4. Use no article for general ideas with plural or uncountable nouns: *I like dogs. Water is important.*

• Wrong: *I am a engineer.* → Right: *I am an engineer.*
• Wrong: *The life is hard.* → Right: *Life is hard.*

Practice: describe your street in four sentences. Circle every noun and ask: new or known? One or many?

Step 3: What's the difference between "few" and "a few"?

This small word "a" changes the whole feeling of the sentence.

Countable nouns have a plural form: *friends, apples, dollars*. Uncountable nouns usually don't: *water, time, money, advice, information*.

• Wrong: *Can you give me some advices?* → Right: *Can you give me some advice?*
• Wrong: *I have a few money.* → Right: *I have a little money.*

In everyday speech, people often say *not many* instead of *few* and *not much* instead of *little*. *Not many people came* sounds more natural than *few people came* in a casual chat.

Practice: write two sentences with "a few" and two with "few" about your week. Read them aloud. Does each one feel positive or negative?

Step 4: Present simple or present continuous?

English has two common present tenses, and beginners often mix them up.

• Present simple is for habits, facts, and routines: *I drink coffee every morning. Water boils at 100 degrees Celsius.*
• Present continuous (am/is/are + -ing) is for things happening right now or around now: *I'm drinking coffee right now. She's studying for an exam this month.*

• Wrong: *I am living in Chicago since 2020.*
• Right: *I have lived in Chicago since 2020.* (More on this in Step 6.)

Trap: some verbs almost never take -ing because they describe states, not actions: *know, want, like, need, believe, understand*.

• Wrong: *I am knowing the answer.* → Right: *I know the answer.*

Practice: write three things you do every day and three things you're doing this week.

Step 5: How do you form the past simple?

Regular verbs add -ed: *work → worked, play → played*. The problem is irregular verbs, which change in their own way: *go → went, buy → bought, take → took*.

There's no trick. You have to learn the common ones. Start with the 20 you'll use most:

1. be → was/were

2. have → had

3. do → did

4. go → went

5. get → got

6. make → made

7. say → said

8. see → saw

9. come → came

10. take → took

11. know → knew

12. think → thought

13. give → gave

14. find → found

15. tell → told

16. buy → bought

17. eat → ate

18. write → wrote

19. leave → left

20. pay → paid

Big rule for questions and negatives: once you use did, the main verb goes back to its base form.

• Wrong: *Did you went to work?* → Right: *Did you go to work?*
• Wrong: *I didn't bought it.* → Right: *I didn't buy it.*

Practice: write five sentences about what you did yesterday. Then turn two of them into questions with "did."

Step 6: When do you use "have done" instead of "did"?

This tense is called the present perfect (have/has + past participle). It connects the past to now.

Use it for:

• Something that started in the past and is still true: *I have worked here for three years.* (I still work here.)
• Life experience with no specific time: *I have been to Mexico.*
• Recent news: *She has lost her keys.* (She can't find them now.)

Use the past simple when you say *when* it happened: *I went to Mexico in 2019.*

• Wrong: *I have seen him yesterday.* → Right: *I saw him yesterday.*

Simple test: if the sentence has *yesterday, last week, in 2019, ago*, use the past simple.

Step 7: At, on, or in for time?

Prepositions of time follow a size pattern: from small to big.

• Wrong: *See you in Monday.* → Right: *See you on Monday.*
• Wrong: *I was born on 1995.* → Right: *I was born in 1995.*

Notice: *in the morning*, but *at night*. That's just how English works. Learn it as a pair.

Step 8: Where do words go in a sentence?

Basic English order is Subject + Verb + Object: *Maria (subject) cooks (verb) dinner (object).*

Three common order mistakes:

1. Adjectives go before the noun: *a red car*, not *a car red*.

2. Adverbs of frequency go before the main verb: *I always eat breakfast*, not *I eat always breakfast*. But they go after "be": *She is always late.*

3. Time usually goes at the end: *I study English every night.*

Step 9: How do you ask a question correctly?

In most questions, you need a helper verb (do, does, did) before the subject.

• Wrong: *Where you live?* → Right: *Where do you live?*
• Wrong: *What time she starts?* → Right: *What time does she start?* (The -s moves to "does.")

With be and can, just flip the order: *You are tired → Are you tired? She can swim → Can she swim?*

Practice: write five questions you might ask a new coworker. Check each one for do/does/did.

Step 10: How do you compare things?

• Short adjectives (one syllable) add -er: *tall → taller, cheap → cheaper*.
• Long adjectives use more: *expensive → more expensive*.
• Adjectives ending in -y change to -ier: *easy → easier, happy → happier*.
• Irregular ones: *good → better, bad → worse, far → farther*.

• Wrong: *This phone is more cheap.* → Right: *This phone is cheaper.*
• Wrong: *My English is more better now.* → Right: *My English is better now.*

How should you practice so the rules stick?

Reading rules is not the same as using them. A simple 15-minute daily plan works better than one long session a week:

1. 5 minutes: review one rule from this list. Just one.

2. 5 minutes: write five sentences about your real life using that rule.

3. 5 minutes: read your sentences out loud. If you can, record yourself and listen back.

Spend two or three days on each step before moving on. After Step 10, go back to Step 1. You'll notice mistakes you didn't see the first time.

Keep a "mistake notebook." Every time someone corrects you, or you catch your own error, write the wrong sentence and the right sentence side by side. Reread it once a week. Your personal mistakes matter more than any list.

Your next step

Tonight, write a short paragraph of five to eight sentences about your day. Then check it against this list in order: verb agreement (Step 1), articles (Step 2), and tense (Steps 4 to 6). Fix what you find, and save both versions in your mistake notebook. Tomorrow, pick the rule you broke most and practice only that one.

FAQ

What is the difference between few and a few?

'A few' means some or enough and sounds positive: I have a few friends here. 'Few' means almost none and sounds negative: Few people came. Both are used with countable nouns.

Which English grammar rule should beginners learn first?

Start with subject-verb agreement, like adding -s after he, she, or it in the present tense. It's the most common everyday mistake and the easiest to fix with daily practice.

How long does it take to learn basic English grammar?

It depends on your practice. A useful plan is 15 minutes a day, spending two or three days on each rule. Going through ten rules this way takes about a month, and then you repeat the cycle.
