    ### 🔠 Letter: E / स — *Enrichment Vocabulary / शब्द समृद्धि*

    #### 📚 Concept:
    - EN: Enrichment Vocabulary  
    - HI: शब्द समृद्धि

    #### 🧠 Type:
    - EN: Enrichment Vocabulary  
    - HI: शब्द समृद्धि

    #### 📖 Description:
    - EN: Improving vocabulary usage by enriching sentences with appropriate adjectives, adverbs, and idioms.  
    - HI: सही विशेषण, क्रिया विशेषण और मुहावरे के साथ वाक्यों को बेहतर बनाना।

    #### 📌 Explanation:
    - EN: Using adjectives, adverbs, synonyms, and idioms enriches sentences for better expression and clarity.  
    - HI: विशेषण, क्रिया विशेषण, पर्यायवाची और मुहावरे वाक्यों को सुंदर और स्पष्ट बनाते हैं।

    ["Enrich the sentence 'The clerk handled the files.' by adding appropriate adjectives and adverbs to improve clarity and vividness without changing the core meaning.", "Enhance the sentence 'The meeting was held.' using idioms related to punctuality and efficiency while maintaining professionalism and clarity.", "Rewrite the sentence 'She types quickly.' using synonyms and enriched vocabulary to make it more formal and suitable for official exam contexts."]

    **HINDI:**
    ["वाक्य 'क्लर्क ने फाइलें संभाली।' में उपयुक्त विशेषण और क्रिया विशेषण जोड़कर वाक्य को विस्तृत बनाएं।", "वाक्य 'बैठक आयोजित की गई।' को समयनिष्ठा और उत्पादकता से जुड़े मुहावरों के साथ पुनर्लेखन करें।", "वाक्य 'वह तेजी से टाइप करती है।' को पर्यायवाची शब्दों से पुनर्लेखन करें जिससे सामान्\u200dय शब्दांश अधिक औपचारिक हो।"]
