Quick answer: Start with seven rules: word order, the verb to be, present simple vs continuous, past simple, a/an/the, questions and negatives. They cover most everyday sentences. Practice one rule at a time, out loud, about 15 minutes a day.↗ Share on X

If you only have a little time, focus on seven grammar rules: basic word order, the verb "to be", present simple vs present continuous, past simple, "a/an/the", making questions, and making negatives. These seven cover most of the sentences you will say and write every day. You do not need to learn every tense or rare exception first. Spend 15 minutes a day on one rule at a time, practice it out loud, and move on only when you can use it without stopping to think.

Below you will find each rule explained in plain words, the mistakes learners make most, and a simple two-week plan.

English has a lot of grammar, but you do not use all of it equally. Most everyday talk is about now, about the past, about what you like and what you want. The seven rules below build those sentences. Rules like "past perfect continuous" or "third conditional" matter later, but you can talk clearly for a long time without them.

Think of it like cooking. You learn to boil water, cut vegetables and fry an egg before you learn a fancy sauce.

Rule 1: How do you order words in English?

The basic order is Subject + Verb + Object. The subject is who does the action. The verb is the action. The object is what receives the action.

• I (subject) drink (verb) coffee (object).
• She reads books.
• They watch movies on Friday.

Time and place usually go at the end: "I drink coffee in the morning." Many languages move words around freely. English does not. If you change the order, the meaning can change or the sentence breaks.

Common mistake: "Coffee I drink every day." → Correct: "I drink coffee every day."

Rule 2: When do you use am, is and are?

The verb "to be" is the most used verb in English. Learn it first.

Use "to be" for names, jobs, feelings, ages, places and descriptions.

Common mistakes:

• "I have 25 years." → Correct: "I am 25 years old."
• "She very happy." → Correct: "She is very happy." (English never drops "to be" in these sentences.)

Rule 3: Present simple or present continuous?

This is where many learners get stuck, so keep it simple:

• Present simple = habits, routines, facts. "I work in a bank." "Water boils at 100 degrees Celsius."
• Present continuous (am/is/are + verb-ing) = right now or these days. "I am working now." "She is studying for an exam this week."

The one small rule in present simple that trips everyone: with he, she, it, add -s to the verb.

• I work → he works
• You like → she likes
• They go → it goes

Common mistakes:

• "He work every day." → "He works every day."
• "I am liking pizza." → "I like pizza." (Verbs about feelings and thoughts, like *like, love, want, know, need*, usually stay in present simple.)

Rule 4: How do you talk about the past?

Use the past simple for finished actions. For most verbs, add -ed:

• walk → walked
• play → played
• watch → watched

Some common verbs are irregular. You have to memorize them, but the list you need at first is short. Start with these ten:

1. go → went

2. have → had

3. do → did

4. make → made

5. get → got

6. see → saw

7. say → said

8. come → came

9. take → took

10. eat → ate

Common mistake: "Yesterday I go to the store." → "Yesterday I went to the store." Words like *yesterday, last week, ago* are your signal to use the past.

Rule 5: When do you use a, an and the?

Articles are small words, but mistakes with them stand out.

• a = one thing, not a specific one, before a consonant sound: *a car, a house, a university* ("university" starts with a "you" sound).
• an = the same, before a vowel sound: *an apple, an hour* (the "h" is silent).
• the = a specific thing both people know about: "Close the door." (the door in this room).

Quick test: if you could say "one", use *a/an*. If the listener knows exactly which one, use *the*.

Common mistakes:

• "She is doctor." → "She is a doctor." (Jobs need *a/an*.)
• "I love the music." when you mean music in general → "I love music."

Rule 6: How do you ask questions?

Most English questions need a helper verb at the start. With present simple, use do/does. With past simple, use did.

Notice two things:

• After *does* and *did*, the main verb goes back to its base form: "Does she live", not "Does she lives".
• With "to be", just swap the order: "He is" → "Is he".

For information questions, put the question word first: Where do you work? What did you eat?

Common mistake: "Where you live?" → "Where do you live?"

Rule 7: How do you make sentences negative?

Negatives follow the same helper pattern as questions.

• Present: I don't (do not) like fish. She doesn't (does not) drive.
• Past: We didn't (did not) see him.
• To be: I'm not hungry. He isn't here. They aren't late.

Common mistakes:

• "I no like fish." → "I don't like fish."
• "She doesn't likes coffee." → "She doesn't like coffee."
• "I don't know nothing." → "I don't know anything." (One negative word is enough.)

What mistakes should you fix first?

If you are short on time, these five errors are worth fixing before anything else because they appear in almost every conversation:

1. Forgetting -s with he/she/it in present simple.

2. Dropping am/is/are.

3. Using present instead of past for finished actions.

4. Missing a/an before jobs and single things.

5. Forgetting do/does/did in questions.

A simple 2-week plan (15 minutes a day)

Tips that make the plan work:

• Say it, don't just read it. Speaking out loud builds the habit faster than reading rules.
• Use your own life. Sentences about you are easier to remember than textbook examples.
• Keep a mistake list. Write down every correction. Review the list once a week.
• Do not chase perfection. Being understood comes first. Polish comes with time.

Your next step

Take a sheet of paper right now and write five sentences about what you did yesterday. Then check each one against the rules above: word order, past simple, irregular verbs, articles and negatives. Circle every mistake and rewrite the sentence correctly. Tomorrow, start Day 1 of the two-week plan and keep your mistake list next to you.

FAQ

Which English grammar rules should a beginner learn first?

Word order, the verb to be, present simple and continuous, past simple, articles (a/an/the), questions with do/does/did and negatives. These build most everyday sentences.

What is the most common English grammar mistake?

Forgetting the -s on the verb with he, she and it in the present simple, as in 'he work' instead of 'he works'. Dropping am/is/are is a close second.

Can I improve my English grammar in 15 minutes a day?

Yes, if you focus on one rule at a time, practice it out loud with sentences about your own life and keep a list of your mistakes to review weekly.
