1 Quick Introduction

English

Transformation means rewriting a sentence in a different form while keeping the same meaning. A statement can become a question; an exclamation can become a plain statement; 'too…to' can become 'so…that'. Exam papers love these because they test how well you really understand structure.

हिन्दी

रूपांतरण (transformation) का अर्थ है किसी वाक्य को भिन्न रूप में लिखना पर अर्थ वही रखना। कथन प्रश्न बन सकता है; विस्मयादिबोधक साधारण कथन बन सकता है; 'too…to' को 'so…that' बनाया जा सकता है। परीक्षाएँ इन्हें पसंद करती हैं क्योंकि ये जाँचती हैं कि आप संरचना को कितना समझते हैं।

2 A Real-Life Situation

Imagine this

You say the same thing five ways:

You: He is too weak to walk. → He is so weak that he cannot walk. → He is very weak, so he cannot walk.

Why this form? All three mean the same — a single idea expressed through different structures. Mastering these swaps makes your writing flexible and helps you answer the 'rewrite as directed' questions that appear in every board paper.

3 The Grammar Rule

Rule & Formula
FromToExample
too…toso…that…nottoo weak to walk → so weak that he can't walk
AffirmativeNegativeOnly he can do it → No one but he can do it
ExclamatoryAssertiveHow sweet it is! → It is very sweet.
InterrogativeAssertiveWho does not love peace? → Everyone loves peace.
Change the FORM, keep the MEANING
She is the best singer = No other singer is as good as she is.

4 Affirmative ↔ Negative, Interrogative ↔ Assertive, Exclamatory ↔ Assertive

Affirmative ↔ Negative (same meaning):

  • Only Ram can solve it. → No one but Ram can solve it.
  • Everyone respects him. → There is no one who does not respect him.
  • He is always late. → He is never on time.

Interrogative ↔ Assertive: a rhetorical question becomes a statement.

  • Who does not love their country? → Everyone loves their country.
  • Is there any use crying? → There is no use crying.

Exclamatory ↔ Assertive:

  • How beautiful the rose is! → The rose is very beautiful.
  • What a shame! → It is a great shame.
Visual — Affirmative ↔ Negative, Interrogative ↔ Assertive, Exclamatory ↔ Assertive
Only he can do it.⇄No one but he can do it.same meaning, different form
1
Worked Example
Make negative (same meaning): Everyone makes mistakes.
Solution

There is no one who does not make mistakes. (or: No one is free from mistakes.)

2
Worked Example
Make assertive: How cleverly she answered!
Solution

She answered very cleverly.

Key Points

  • Affirmative ↔ negative keeps the meaning (Only X → No one but X)
  • Rhetorical question ↔ statement (Who doesn't…? → Everyone…)
  • Exclamatory → assertive uses 'very/great' (How sweet! → very sweet)

5 Simple ↔ Compound ↔ Complex & too…to / so…that

The same idea can be a simple, compound, or complex sentence:

  • Simple: Being ill, he stayed home.
  • Complex: As he was ill, he stayed home.
  • Compound: He was ill, so he stayed home.

Common conversions:

  • Simple → Complex: use a clause. He confessed his guilt. → He confessed that he was guilty.
  • Complex → Compound: split into two independent clauses with a conjunction.

Removing 'too…to': 'too + adjective + to + verb' becomes 'so + adjective + that + subject + cannot/could not + verb':

  • He is too weak to walk. → He is so weak that he cannot walk.
  • It was too dark to see. → It was so dark that we could not see.
1
Worked Example
Remove 'too…to': She is too tired to continue.
Solution

She is so tired that she cannot continue.

2
Worked Example
Simple → complex: I know the answer. (use a noun clause)
Solution

I know what the answer is.

Key Points

  • One idea can be simple, compound or complex
  • Simple → complex by adding a clause; complex → compound by splitting
  • too + adj + to → so + adj + that + … cannot/could not
