3.1 Intuition: What Is Grammar?
Think of grammar as the engine of a car. The car (your ideas) might look good, but without a working engine (correct grammar), it cannot move. Grammar is the system that makes your words work together to create clear meaning.
Real-world context: Imagine you text a friend: "Going store need buy milk." Your friend understands, but barely. Now imagine writing an exam answer the same way. The examiner will not guess what you mean. Proper grammar = proper communication. Every word in English belongs to a part of speech — a category that tells you how the word functions in a sentence.

| Relative | who, whom, which, that |
Example Without Pronouns (Bad)

Example With Pronouns (Good)

3.8 Preposition
A preposition shows the relationship between a noun/pronoun and another word in the sentence.
Prepositions of Time
| Preposition | Use | Example |
|---|---|---|
| at | Specific time | at 5 PM, at midnight, at noon |
| on | Day/date | on Monday, on July 4th |
| in | Month/year/period | in March, in 2024, in the morning |
| by | Deadline | by Friday, by 6 PM |

| in | Enclosed space | in the room, in the box |
| under | Below | under the bed |
| between | In the middle of two | between A and B |
| among | In a group | among friends |
Common Preposition Mistakes
| ❌ Wrong | ✅ Correct | Explanation |
|---|---|---|
| "I am in the bus" | "I am on the bus" | Large vehicles use "on" |
| "Discuss about this" | "Discuss this" | No preposition needed after "discuss" |
| "Pay for attention" | "Pay attention to" | "Attention" takes "to" |
| "In Monday" | "On Monday" | Days use "on" |
3.9 Conjunction
A conjunction connects words, phrases, or clauses.
| Type | Function | Examples |
|---|---|---|
| Coordinating (FANBOYS) | Connects equal elements | For, And, Nor, But, Or, Yet, So |
| Subordinating | Connects dependent + independent clause | because, although, while, if, when, since |
| Correlative | Pairs that work together | either...or, neither...nor, not only...but also |
Example
Ravi and (coordinating) Priya went to the store because (subordinating) they needed groceries. Neither Ravi nor (correlative) Priya had a car.
3.10 Determiner
A determiner introduces a noun and provides context (which one, how many, whose).
| Type | Examples |
|---|---|
| Articles | a, an, the |
| Demonstratives | this, that, these, those |
| Possessives | my, your, his, her, its, our, their |
| Quantifiers | some, any, many, much, few, several |
| Numbers | one, two, three, first, second |
3.11 Interjection
An interjection expresses sudden emotion. It is often followed by an exclamation mark.
Wow! That is amazing. Ouch! That hurt. Oh no! I forgot my keys. Hey! Wait for me.
3.12 Subject-Verb Agreement
The subject and verb must agree in number (singular/plural).
Basic Rule
Singular subject → Singular verb (verb + s) Plural subject → Plural verb (verb without s)
| Subject | Verb | Example |
|---|---|---|
| He / She / It | eats (singular) | "She eats breakfast." |
| I | eat (plural) | "I eat breakfast." |
| They / We / You | eat (plural) | "They eat breakfast." |
| The student | writes | "The student writes essays." |
| The students | write | "The students write essays." |
Special Cases
| Rule | Example |
|---|---|
| Each/Everone/Someone → singular | "Everyone is" (not "are") here. |
| Neither/Nor → verb agrees with closest noun | "Neither the teacher nor the students are ready." |
| Either/Or → verb agrees with closest noun | "Either the students or the teacher is wrong." |
| Collective nouns → singular (group as unit) | "The team plays well." |
| Uncountable nouns → singular | "The information is correct." |
| Titles → singular | "The Chronicles of Narnia is a classic." |
| Mathematics/Physics/News → singular | "Politics is complicated." |
Common Agreement Errors
| ❌ Wrong | ✅ Correct | Why |
|---|---|---|
| "He don't like coffee." | "He doesn't like coffee." | He = third person singular = doesn't |
| "The group are meeting." | "The group is meeting." | Group = singular collective noun |
| "Everyone are happy." | "Everyone is happy." | Everyone = always singular |
| "Neither of them are correct." | "Neither of them is correct." | Neither = singular |
3.13 Articles: A, An, The
Articles are a type of determiner. They tell us whether we are talking about something specific or general.
| Article | Use | Example |
|---|---|---|
| A | Before consonant SOUND (not letter) | a book, a university ("you" sound), a one-time event ("w" sound) |
| An | Before vowel SOUND | an apple, an hour ("ow" sound), an honest man |
| The | Specific item already known | the book I told you about, the sun, the moon |
| No article | General plural, uncountable | "I love books." (general) / "Water is essential." |
Article Rules
| Rule | Correct | Incorrect |
|---|---|---|
| First mention → "a/an" | "I saw a dog." | "I saw dog." |
| Second mention → "the" | "The dog was barking." | "A dog was barking." (wrong if same dog) |
| Unique things → "the" | "The Earth is round." | "Earth is round." (possible but less natural) |
| Superlatives → "the" | "She is the best." | "She is best." |
| General plurals → no article | "Cats are furry." | "The cats are furry." (specific group, not general) |

| Sentence | Part of Speech Analysis |
|---|---|
| ① | Article + Adjective + Noun + Adverb + Verb + Article + Adjective + Noun + Preposition + Adjective + Noun |
| ② | Pronoun + Verb + Pronoun + Adjective |
| ③ | Conjunction + Pronoun + Verb Phrase + Article + Noun + Conjunction + Pronoun + Verb + Adverb + Adjective |
| ④ | Interjection + Determiner + Article + Noun |

4. Common Pitfalls
Pitfall 1: Subject-Verb Agreement with Interrupting Phrases
- Mistake: "The box of chocolates are on the table."
- Why: Students match verb with "chocolates" (plural) instead of "box" (singular subject)
- How to catch it: Ignore the phrase "of chocolates" — the subject is "box"
- Correct: "The box of chocolates is on the table."
Pitfall 2: Confusing Adjectives and Adverbs
- Mistake: "She sings beautiful." (should be "beautifully")
- Why: Students think every descriptive word is an adjective
- How to catch it: If the word describes a VERB (how she sings), use an adverb (-ly)
- Correct: "She sings beautifully."
Pitfall 3: Using "a" Before Vowel Sounds
- Mistake: "a apple" (should be "an apple")
- Why: Students look at the letter, not the sound
- How to catch it: Say the word aloud. If it starts with a vowel SOUND (even if the letter is a consonant), use "an"
- Correct: "an apple," "an hour," "a university"
