📚 Grade 9-12🟡 Medium⏱️ 5-10 min

Problem

Should the verb be singular (is) or plural (are) in the sentence: 'I would argue that the body, and especially the fingers, are also seen to be exotic'? Consider whether 'especially' should be set off by commas and discuss proper English usage.

🎯 What You'll Learn

  • apply subject-verb agreement rules to compound subjects connected by 'and'
  • understand when to use commas with parenthetical elements like 'especially'
  • recognize how sentence structure affects grammatical correctness

Prerequisites: understanding of subjects and verbs, knowledge of compound subjects, understanding of coordinating conjunctions

💡 Quick Summary

Great question — this touches on one of the trickiest areas in English grammar: subject-verb agreement when extra information sneaks into the middle of a sentence! Before you decide between "is" and "are," try this mental experiment: what happens if you completely remove the phrase "especially the fingers" from the sentence — what word is left as your true subject, and is it singular or plural? It's also worth asking yourself what the word "especially" is actually doing here — is it introducing a brand new, equal subject, or is it zooming in to highlight a part of something already mentioned? Once you've identified the true grammatical subject, think about how parenthetical phrases — those little "bonus detail" additions — are typically set off from the rest of a sentence punctuation-wise. You already have the instincts to work through this; just trust your analysis of the sentence structure over what might *sound* natural at first glance, since our ears can sometimes be fooled by the noun closest to the verb. Give it a try and see what you come up with!

1. What We're Solving

We need to figure out two things:

  • Should the verb be "is" or "are" in the sentence?
  • Should "especially the fingers" be surrounded by commas?
These questions are connected, making this an interesting puzzle.

---

2. The Approach

The key skill here is identifying the true grammatical subject of the sentence. In English, the verb must agree with the subject — but sometimes extra information gets tucked between the subject and the verb, which can mislead us into choosing the wrong verb form.

---

3. Step-by-Step Solution

Step 1: Find the Core Subject

Look at the sentence: > "...the body, and especially the fingers, are also seen to be exotic"

Ask yourself: What is the main thing being discussed? Strip away everything between the commas:

> "...the body... are also seen to be exotic"

The primary subject is "the body" — singular! ✅

---

Step 2: Understand What "Especially the Fingers" Actually Does

The phrase "especially the fingers" is what grammarians call a parenthetical modifier — it adds bonus detail but doesn't change the subject.

Think of it like a whispered aside: > "The body — yes, particularly the fingers — is exotic."

It's not creating a new, equal subject. It's saying within the body, the fingers are a highlight. The fingers are part of the body being discussed.

Compare this to a true compound subject:

  • "The body and the fingers are exotic" — here both are equal partners → plural verb ✓
  • "The body, and especially the fingers, is exotic" — "especially" signals subordination → singular verb ✓
The word "especially" is your clue! It means "most notably among these" — it doesn't add a new subject, it spotlights part of the existing one.

---

Step 3: The Comma Question

Should "especially the fingers" be set off by commas? Yes, absolutely!

Here's why:

  • The phrase is non-essential (parenthetical) — the sentence works without it
  • Commas signal to the reader: "this is extra information, not the main clause"
  • Without commas, readers might think "body and fingers" form a compound subject, causing confusion
> ✅ "the body, and especially the fingers, is also seen to be exotic"

The commas actually reinforce the singular verb choice by visually separating the parenthetical phrase.

---

Step 4: Check Your Ear vs. Your Brain

You might feel like "are" sounds more natural — and that's completely understandable. When we hear "fingers," our brain wants a plural verb. This is called attraction error — the verb gets "attracted" to the nearest noun rather than the true subject.

> "The body... is" ← what the grammar requires > "...the fingers... are" ← what our ear wants (but this is incorrect here)

Trust your analysis over your instinct in cases like this! 🧠

---

4. The Answer

| Feature | Correct Choice | Why | |---|---|---| | Verb form | is (singular) | "The body" is the true subject | | Commas around "especially the fingers" | Yes | It's a parenthetical modifier |

Corrected sentence: > "I would argue that the body, and especially the fingers, is also seen to be exotic."

---

5. Memory Tip 💡

The "ESPECIALLY test": Whenever you see especially, particularly, notably, or above all tucked between commas, ask: "Is this phrase adding a NEW subject or HIGHLIGHTING part of the existing one?"

If it's highlighting → keep the original verb agreement

Think of it this way: "especially" zooms in 🔍 — it doesn't multiply!

---

You're asking exactly the right kind of questions about grammar. This is a nuance that even experienced writers get wrong. 🌟
