The Exclusive One: Only One of + Plural Noun + Relative Pronoun + Singular Verb

विशेष 'एक': 'Only One of + Plural Noun + Relative Pronoun' के साथ Singular Verb

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.

💡 Fun Memory Story & Formula Trick:
💡 '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: 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.
📌 Key Grammar Rules & Formulas:
  • âœĻ Rule 1: Structure: 'Only one of + Plural Noun + (who/which/that) + Singular Verb'.
  • âœĻ 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'.
  • âœĻ 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).

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."

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'.

Subject-Verb Agreement 🏷ī¸ One of + Plural Noun

Group Power: One of + Plural Noun + Relative Pronoun + Plural Verb

समूह की शक्ति: 'One of + Plural Noun + Relative Pronoun' के साथ Plural Verb

When a relative pronoun (who, which, that) immediately follows 'One of + Plural Noun', the verb within the relative clause agrees with the *plural noun* (the antecedent of the relative pronoun), not with 'One'. The relative pronoun refers to the group, not the single item.

💡 Fun Memory Story & Formula Trick:
💡 Think of the Relative Pronoun (who/which/that) as a 'Group Spotlight'. It shines directly on the *group* (the plural noun) right before it, making the verb in its clause agree with the group, not the 'One' far away. Spotlight on the crowd, not the individual!
💡 सापेक्ष सर्वनाम (who/which/that) को 'समूह स्पॉटलाइट' के रूप में सोचें। यह सीधे अपने से ठीक पहले आने वाले *समूह* (बहुवचन संज्ञा) पर चमकता है, जिससे इसके खंड में क्रिया समूह के साथ सहमत होती है, न कि दूर के 'One' के साथ। भीड़ पर स्पॉटलाइट, व्यक्ति पर नहीं!
⚠️ Exam Trap: This is a classic trap! Students often mistakenly make the verb in the relative clause singular, thinking it still refers to 'One'. Always check what the relative pronoun is actually referring to!
📌 Key Grammar Rules & Formulas:
  • âœĻ Rule 1: Structure: 'One of + Plural Noun + (who/which/that) + Plural Verb'.
  • âœĻ Rule 2: The relative pronoun (who, which, that) refers to the *plural noun* that precedes it, not 'One'. Therefore, the verb in the relative clause must be plural.
  • âœĻ Rule 3: Example: 'She is one of the scientists who **believe** in climate change.' (Here, 'who' refers to 'scientists', so the verb 'believe' is plural).

Choose the correct option to complete the sentence: "He is one of the authors who ______ won the prestigious literary award."

The relative pronoun 'who' refers to 'authors' (plural noun). Therefore, the verb in the relative clause must be plural. 'Have' is the correct plural verb form.

Subject-Verb Agreement 🏷ī¸ One of + Plural Noun

The Lone Leader: One of + Plural Noun + Singular Verb

अकेला नायक: 'One of + Plural Noun' के साथ Singular Verb

This rule clarifies that when you use the phrase 'One of + Plural Noun', the actual subject of the sentence is 'One', not the plural noun that follows. Therefore, the verb that accompanies this structure must always be singular.

💡 Fun Memory Story & Formula Trick:
💡 Imagine 'One' as the VIP (Very Important Person) and the 'Plural Noun' as its entourage. The verb always bows down to the VIP ('One'), never to the crowd! So, 'One' = Singular Verb. VIP (One) gets singular treatment!
💡 कल्पना कीजिए 'One' एक VIP (बहुत महत्वपूर्ण व्यक्ति) है और 'Plural Noun' उसका दल है। क्रिया हमेशा VIP ('One') के सामने झुकती है, भीड़ के सामने कभी नहीं! तो, 'One' = Singular Verb। VIP (One) को एकवचन सम्मान मिलता है!
⚠️ Exam Trap: Examiners often place a plural noun right before the verb to trick you into using a plural verb. Remember, the subject is 'One', not the plural noun in the 'of' phrase!
📌 Key Grammar Rules & Formulas:
  • âœĻ Rule 1: The core structure is 'One of + Plural Noun + Singular Verb'. The verb agrees with 'One', which is singular.
  • âœĻ Rule 2: The plural noun (e.g., 'friends', 'books', 'problems') acts as an object of the preposition 'of' and specifies the group from which 'one' is chosen.
  • âœĻ Rule 3: Example: 'One of the new employees is exceptionally skilled.' (Here, 'is' agrees with 'One', not 'employees').

Identify the error in the following sentence: "One of the most challenging tasks in my career have been managing this project."

The subject of the sentence is 'One', not 'tasks'. Therefore, the verb must be singular. 'Have been managing' should be replaced with 'has been managing' to agree with the singular subject 'One'.
