Welcome to the World of Agreement!
Hi there! Have you ever noticed that sentences are a bit like a team sport? For a team to win, everyone has to work together. In English, the two most important players are the Subject (the person or thing doing the action) and the Verb (the action itself).
In this chapter, we are going to learn about Subject-Verb Agreement. This simply means that the subject and the verb must match each other in "number." If the subject is singular (one), the verb must be singular. If the subject is plural (more than one), the verb must be plural. When they match, your writing sounds smooth and professional!
1. The Basic Rule: Singular vs. Plural
The most important thing to remember is the "S" Rule. It works like a see-saw:
Singular Subjects: When you have one person or thing, the verb usually needs an -s or -es at the end (in the present tense).
Example: The dog barks. (One dog + verb with "s")
Plural Subjects: When you have more than one, the verb stays "plain" and does not need an -s.
Example: The dogs bark. (Many dogs + plain verb)
Quick Memory Trick: The Seesaw Balance
Think of the letter S as a weight.
- If the Subject doesn't have an S (singular), the Verb takes the S to balance the see-saw.
- If the Subject already has an S (plural), the Verb doesn't need it!
Key Takeaway: Singular subjects take singular verbs (with -s); plural subjects take plural verbs (no -s).
2. The "Power of And" (Compound Subjects)
When you join two subjects together using the word and, they become a Compound Subject. Because \( 1 + 1 = 2 \), the subject is now plural.
Example: Peter and Mary are going to the park.
Example: The cat and the dog play together.
Did you know?
Even if both people are singular, the word and acts like a plus sign, making the whole group plural!
Key Takeaway: Subjects joined by and almost always take a plural verb.
3. The "Neighbor Rule" (Or / Nor)
Sometimes subjects are joined by or or nor. This is different from "and" because we aren't adding them together; we are choosing between them.
When using or or nor, the verb agrees with the subject closest to it. Think of it as the Neighbor Rule—the verb only cares about its immediate neighbor!
Example: Either the teacher or the students write on the board. (Students is plural and closer to the verb, so we use "write").
Example: Either the students or the teacher writes on the board. (Teacher is singular and closer, so we use "writes").
Key Takeaway: With or/nor, look at the noun right next to the verb to decide if it needs an -s.
4. The "Lonely Ones" (Indefinite Pronouns)
Don't worry if this part seems tricky at first! Some words sound like they are plural, but they are actually Singular. We call these Indefinite Pronouns.
Words like Each, Everyone, Someone, Everybody, and Nobody are always singular.
Example: Everyone is happy today. (Not "Everyone are")
Example: Each of the players has a ball.
Mnemonic: The "One" and "Body" Rule
If a word ends in -one (Someone, Everyone) or -body (Somebody, Everybody), treat it like One person. One person is singular!
Key Takeaway: Words like "Each" and "Everyone" are singular and need singular verbs.
5. Watch Out for "Extra Baggage" (Phrases in Between)
Sometimes, extra words crawl in between the subject and the verb to try and confuse you. Phrases like along with, as well as, or including are just "extra baggage." They do not change the subject!
The Suitcase Analogy
Imagine a traveler (the subject) carrying three suitcases (the extra phrase). Even though there are many suitcases, there is still only one traveler. The verb only follows the traveler.
Example: The captain, along with his sailors, is on the ship.
In this sentence, "captain" is the subject. The "sailors" are just extra baggage. Since "captain" is singular, we use "is."
Common Mistake to Avoid:
Wrong: The cake, as well as the cookies, are delicious.
Right: The cake, as well as the cookies, is delicious.
(The subject is "cake," not the cookies!)
Key Takeaway: Ignore phrases starting with "as well as" or "along with" when choosing your verb.
6. Collective Nouns (The Group Rule)
A Collective Noun is a word that describes a group of people, like team, family, class, or audience.
In most cases, we think of the group acting as one single unit. Therefore, we use a singular verb.
Example: My family is very large.
Example: The team plays well together.
Key Takeaway: Treat groups (team, class, family) as one singular thing.
Summary: Your Subject-Verb Checklist
Before you finish your sentence, ask yourself these three steps:
Step 1: Who is the real Subject? (Ignore the "baggage"!)
Step 2: Is the subject Singular or Plural?
Step 3: Does the Verb match? (Remember: Singular subjects usually need a verb with an -s!)
Great job! You are now ready to make sure your subjects and verbs live in perfect harmony!
