1 Quick Introduction
A strong vocabulary lets you say exactly what you mean. This chapter sharpens four tools: synonyms (same meaning), antonyms (opposite meaning), homophones (sound alike, spelt differently), and idioms (phrases with a hidden meaning). Together they make your English clearer and more colourful.
अच्छी शब्द-सम्पदा (Vocabulary) से आप ठीक वही कह पाते हैं जो आपका अर्थ है। यह अध्याय चार उपकरण तेज़ करता है: पर्यायवाची (synonyms), विलोम (antonyms), समोच्चारित (homophones), और मुहावरे (idioms)। ये मिलकर आपकी अंग्रेज़ी को स्पष्ट और रोचक बनाते हैं।
2 A Real-Life Situation
You write a message but autocorrect plays tricks:
Wrong: Their going to they're house over there.
Right: They're going to their house over there.
3 The Grammar Rule
| Tool | Meaning | Example |
|---|---|---|
| Synonym | same meaning | happy = glad |
| Antonym | opposite meaning | happy × sad |
| Homophone | same sound, diff. spelling | to / too / two |
| Idiom | hidden, figurative meaning | a piece of cake = easy |
4 Synonyms, Antonyms & Homophones
Synonyms are words with the same or similar meaning: big = large, fast = quick, happy = glad. They help you avoid repeating the same word.
Antonyms are words with opposite meanings: hot × cold, begin × end, ancient × modern.
Homophones sound the same but are spelt differently and mean different things:
| Word | Meaning |
|---|---|
| their | belonging to them |
| there | that place |
| they're | they are |
| to / too / two | towards / also / 2 |
| write / right | to put on paper / correct |
A related idea is the homonym: one spelling, two meanings — bat (animal / cricket bat).
Synonym: courageous; Antonym: cowardly.
They're — it means 'They are coming'.
Key Points
- Synonyms = same meaning; antonyms = opposite meaning
- Homophones sound alike but differ in spelling and meaning
- Homonyms have one spelling with two meanings (bat)
5 One-Word Substitution & Idioms
One-word substitution replaces a whole phrase with a single precise word:
| Phrase | One Word |
|---|---|
| a person who cannot read or write | illiterate |
| one who studies stars | astronomer |
| a place where books are kept | library |
| animals that eat only plants | herbivores |
Idioms are colourful phrases whose meaning is not literal:
- a piece of cake = very easy
- once in a blue moon = very rarely
- let the cat out of the bag = reveal a secret
- break the ice = start a conversation
dentist.
Something very easy — it is an idiom, not about real cake.
Key Points
- One-word substitution = one precise word for a phrase
- Idioms have a figurative (hidden) meaning
- 'a piece of cake' = easy; 'break the ice' = start talking
