📚 Main English Grammar Rules You Should Know
1. Parts of Speech
Every sentence is made up of different types of words. These are called parts of speech.
The main types include:
- Nouns (names of people, places, things)
- Verbs (actions or states)
- Adjectives (describe nouns)
- Adverbs (describe verbs)
- Pronouns (replace nouns)
- Prepositions (show position or direction)
- Conjunctions (connect words or sentences)
👉 Start with our full guide on parts of speech to understand how sentences are built.
2. Sentence Structure
Basic English sentences follow this structure:
Subject + Verb + Object
Examples:
- She reads books.
- They play football.
- I eat breakfast.
Good sentence structure helps your writing become clear and easy to understand.
3. Subject-Verb Agreement
The verb must match the subject in number.
Examples:
- He runs every day.
- They run every day.
Common mistake:
❌ He run every day
✅ He runs every day
4. Tenses
Tenses show when an action happens.
The three main tenses are:
- Present (I eat)
- Past (I ate)
- Future (I will eat)

5. Articles (A, An, The)
Articles are used before nouns.
- A / An → general
- The → specific
Examples:
- I saw a dog.

Prepositions show relationships between words.
Examples:
- The book is on the table.
- She is sitting in the room.
