1. WHAT ARE CONDITIONAL SENTENCES? (परिभाषा)
| Definition | Hindi Definition | Basic Concept |
|---|---|---|
| Conditional sentences are used to express that one thing depends on another. They have two parts: the if-clause (condition) and the main clause (result). | सशर्त वाक्य उन स्थितियों को व्यक्त करने के लिए उपयोग किए जाते हैं जहाँ एक बात दूसरी बात पर निर्भर करती है। इनके दो भाग होते हैं: यदि-उपवाक्य (शर्त) और मुख्य उपवाक्य (परिणाम)। | If X happens, then Y happens. (यदि X होता है, तो Y होता है।) |
