📚 Class 10 CBSE – English Grammar
(A concise, study‑friendly guide for the CBSE syllabus)
1. Introduction
Grammar is the backbone of the English language. It gives structure to sentences, helps us convey ideas clearly, and is the foundation for all other language skills. In Class 10, you will learn to identify and use the major parts of speech, tenses, voices, and other grammatical structures.
2. Simple Explanation of Core Concepts
| Concept | What it means | Why it matters |
|---|---|---|
| Part of Speech | The role a word plays in a sentence (noun, pronoun, verb, adjective, adverb, etc.). | Helps decide word order and meaning. |
| Tenses | Show when an action happens – past, present, future (simple, continuous, perfect, perfect‑continuous). | Communicates time accurately. |
| Voice | Whether the subject performs or receives the action (active vs. passive). | Shifts emphasis or style. |
| Direct & Indirect Speech | Reporting what someone said literally or in your own words. | Useful for summarising conversations. |
| Subject–Verb Agreement | Subject and verb must agree in number (singular/plural). | Prevents grammatical errors. |
| Adjectives & Adverbs | Descriptive words for nouns and verbs (and other words). | Adds detail and colour. |
| Comparatives & Superlatives | Compare two or more items. | Expresses degree of quality. |

| Passive | Object + (be) + Past Participle + (by + Subject) | The lesson was explained by the teacher. |
Tip: Use passive when the doer is unknown, irrelevant, or you want to emphasise the action.
3.5 Direct & Indirect Speech
| Feature | Direct Speech | Indirect Speech |
|---|---|---|
| Quotations | “I am happy,” he said. | He said that he was happy. |
| Pronoun shift | I → He | I → He |

| Time words | today, now → that day, then | today → that day |
3.6 Subject–Verb Agreement
| Rule | Example |
|---|---|
| Singular subject → singular verb | The list of items is on the table. |
| Plural subject → plural verb | The teachers are available. |
