Rule Concept Overview

When the phrase 'Only one of + Plural Noun' is used, the word 'Only' changes the focus. In this specific case, the relative pronoun (who, which, that) refers back to 'one' (emphasized by 'only'), making the verb in the relative clause singular.

जब 'Only one of + Plural Noun' वाक्यांश का उपयोग किया जाता है, तो 'Only' शब्द ध्यान केंद्रित करने के तरीके को बदल देता है। इस विशेष मामले में, सापेक्ष सर्वनाम (who, which, that) 'one' (जो 'only' द्वारा बल दिया गया है) को संदर्भित करता है, जिससे सापेक्ष खंड में क्रिया एकवचन हो जाती है।

๐Ÿ“Œ Key Grammar Rules & Formulas

Rule 1: Structure: 'Only one of + Plural Noun + (who/which/that) + Singular Verb'.
नियम 1: संरचना: 'Only one of + Plural Noun + (who/which/that) + Singular Verb'।
Rule 2: The word 'Only' isolates 'one' as the unique subject, even within the relative clause. The relative pronoun now refers to 'the only one'.
नियम 2: 'Only' शब्द 'one' को अद्वितीय कर्ता के रूप में अलग करता है, सापेक्ष खंड के भीतर भी। सापेक्ष सर्वनाम अब 'the only one' को संदर्भित करता है।
Rule 3: Example: 'He is the only one of the students who **has** completed the advanced course.' (Here, 'who' refers to 'the only one', so 'has' is singular).
नियम 3: उदाहरण: 'He is the only one of the students who **has** completed the advanced course.' (यहाँ, 'who' 'the only one' को संदर्भित करता है, इसलिए 'has' एकवचन है)।

เคธเคฌเคธเฅ‡ เค†เคธเคพเคจ Trick & Memory Formula

Use this proven formula shortcut and mnemonic trick to lock this rule into permanent memory:

💡 'Only' is like a super-exclusive VIP pass for 'One'. It makes 'One' so special and unique that even if there's a crowd (plural noun) around, the spotlight (relative pronoun) still focuses solely on that 'One'. So, 'Only One' = Super Singular Verb!
💡 'Only' 'One' के लिए एक सुपर-एक्सक्लूसिव VIP पास की तरह है। यह 'One' को इतना खास और अद्वितीय बनाता है कि भले ही आसपास भीड़ (बहुवचन संज्ञा) हो, स्पॉटलाइट (सापेक्ष सर्वनाम) अभी भी केवल उस 'One' पर केंद्रित रहता है। तो, 'Only One' = सुपर सिंगुलर वर्ब!

Exam Trap Alert (Error Spotting Trap)

⚠️ Exam Trap: This is a tricky variation! Students often confuse this with the previous rule and use a plural verb. The presence of 'Only' is the crucial differentiator that demands a singular verb in the relative clause.
⚠️ परीक्षा में भ्रम से बचने की चेतावनी: यह एक मुश्किल भिन्नता है! छात्र अक्सर इसे पिछले नियम के साथ भ्रमित करते हैं और बहुवचन क्रिया का उपयोग करते हैं। 'Only' की उपस्थिति महत्वपूर्ण अंतर है जो सापेक्ष खंड में एकवचन क्रिया की मांग करती है।

Identify the part of the sentence that contains an error: "She is the only one of the candidates who were selected for the final interview round."

वाक्य के उस भाग को पहचानें जिसमें त्रुटि है: "She is the only one of the candidates who were selected for the final interview round."
The phrase 'the only one' emphasizes singularity. Therefore, the relative pronoun 'who' refers to 'the only one', requiring a singular verb. 'Were selected' should be changed to 'was selected'.
'the only one' वाक्यांश एकवचन पर जोर देता है। इसलिए, सापेक्ष सर्वनाम 'who' 'the only one' को संदर्भित करता है, जिसके लिए एकवचन क्रिया की आवश्यकता होती है। 'Were selected' को 'was selected' में बदलना चाहिए।

Mastering Along with / Together with / As well as: Spotting the True Subject
๐Ÿ’ก 💡 Think of it like a 'Grammar Filter'. When you see 'along with', 'together with', or 'as well as', put a mental filter over them. Whatever is *before* the filter is your main subject, and that's what the verb must agree with. Everything *after* the filter is just extra detail!
Along with / Together with / As well as: The 'Side-Dish' Connectors
๐Ÿ’ก 💡 Imagine you're ordering a meal. The main dish (Subject 1) determines the plate size and cutlery (the verb). The 'along with' items are just side dishes – they come *with* the main dish but don't change how you eat the main course! So, the verb always matches the 'main dish' (Subject 1).
The 'First Subject Rules All' with Along with / Together with / As well as
๐Ÿ’ก 💡 Think of it as the 'VIP Rule'! The FIRST subject is the VIP (Very Important Person) and the verb only listens to the VIP. The people 'along with' or 'together with' are just escorts or companions; they don't get to decide the verb's form. The VIP (Subject 1) calls the shots!
