    ### 🔠 Letter: N / न — *Negation Forms / नकारात्मक रूप*

    #### 📚 Concept:
    - EN: Negation Forms  
    - HI: नकारात्मक रूप

    #### 🧠 Type:
    - EN: Negation Forms  
    - HI: नकारात्मक रूप

    #### 📖 Description:
    - EN: Converting affirmative sentences into their correct negation forms and vice versa.  
    - HI: सकारात्मक वाक्यों को सही नकारात्मक रूपों में बदलना और इसके विपरीत।

    #### 📌 Explanation:
    - EN: Transforming positive sentences into their negative forms requires understanding auxiliaries and word order.  
    - HI: सकारात्मक वाक्यों को नकारात्मक में बदलने के लिए सहायक क्रिया और शब्द क्रम समझना जरूरी है।

    #### ➗ Formula or Relation:
    - EN: **Positive Sentence + Negation Word (not/never) + Auxiliary Verb = Negative Sentence**  
    - HI: **सकारात्मक वाक्य + नकारात्मक शब्द (not/never) + सहायक क्रिया = नकारात्मक वाक्य**

    #### 💡 Example Questions:
    **ENGLISH:**
    ["Convert the sentence 'The typist completes the transcription accurately every day.' into its correct negative form without altering the meaning of repeated accuracy.", "Rewrite the sentence 'The team will finish the report by tomorrow morning.' as a negative sentence expressing the same timeline constraint.", "Change the following sentence to negative: 'All the forms have been submitted before the deadline set by the department.' Ensure the sentence remains grammatically correct."]

    **HINDI:**
    ["वाक्य 'टाइपिस्ट हर दिन सटीक रूप से ट्रांसक्रिप्शन पूरा करता है।' का सही नकारात्मक रूप बनाएं, जिससे मूल अर्थ परिवर्तित न हो।", "वाक्य 'टीम रिपोर्ट कल सुबह तक समाप्त कर देगी।' को नकारात्मक रूप में लिखें जिसमें समयसीमा बनी रहे।", "वाक्य 'सभी फॉर्म अंतिम तिथि से पहले जमा किए गए हैं।' का नकारात्मक रूप बनाएं और व्याकरणिक रूप से सही रखें।"]
