🎯 What You'll Learn

  • Understand nuanced grammar rules
  • Recognize how modifiers affect grammatical construction

Prerequisites: Basic English grammar, Understanding of subject-verb agreement

💡 Quick Summary

Hi there! This is a fantastic grammar question about subject-verb agreement, which can be really tricky when dealing with collective phrases like "a growing number of." Here's what I'd like you to think about: when you have the phrase "a growing number of students," what do you think is the true grammatical subject - is it the word "number" or is it "students"? Also, consider this - even if the grammatical subject might technically be one thing, what is the sentence really emphasizing or focusing on in terms of meaning? I'd encourage you to think about similar phrases you might use naturally, like "a lot of students" or "many students" - what verb would you instinctively choose with those? The key concept here is understanding that sometimes in English, meaning can override strict grammatical rules, especially with certain collective expressions. Give it a try by thinking about what the phrase is really trying to communicate!

Step-by-Step Explanation

TinyProf's Grammar Guide 📚

1. What We're Solving:

We need to figure out whether to use "is" or "are" with the phrase "a growing number of students" - this is a tricky subject-verb agreement question that confuses many people!

2. The Approach:

The key is identifying the TRUE subject of the sentence. Sometimes what looks like the subject isn't actually what the verb needs to agree with. We'll need to break down the phrase and understand which part controls the verb choice.

3. Step-by-Step Solution:

Step 1: Break down the phrase "A growing number of students" has two potential subjects:

  • "number" (singular)
  • "students" (plural)
Step 2: Identify the grammatical subject The grammatical subject is "number" - it's a singular noun that's being modified by "growing" and followed by the prepositional phrase "of students."

Step 3: Apply the rule Even though "students" is plural and might sound more natural with "are," the verb must agree with the grammatical subject "number," which is singular.

Step 4: Consider the meaning While grammatically "number" is singular, when we say "a number of," we're really thinking about the multiple items (students). This creates a special case in English.

Step 5: Choose based on accepted usage In modern English, "a number of" is treated as plural because the meaning focuses on the multiple items, not the word "number" itself.

4. The Answer:

"There ARE a growing number of students..." is correct.

The phrase "a growing number of" (like "a number of") takes a plural verb because the emphasis is on the multiple students, not on the singular word "number."

5. Memory Tip:

Think of it this way: "A number of" = "Several" or "Many"
  • You wouldn't say "Several students IS coming" ❌
  • You'd say "Several students ARE coming" ✅
  • So: "A number of students ARE coming" ✅
Bonus tip: This is different from "THE number," which is singular: "The number of students IS increasing." Notice how "the number" focuses on the actual quantity, while "a number of" focuses on the multiple items!

Keep practicing - subject-verb agreement takes time to master, but you're doing great by asking these thoughtful questions! 🌟
