Subject-Verb Agreement

Master the fundamental rule that makes your English sound natural! Learn how subjects and verbs work together in perfect harmony.

🎯 The Golden Rule

The subject and verb must agree in number - if one is singular, the other must be singular too!
1️⃣
Singular
One subject takes a singular verb
Add -s, -es, or -ies to the verb
She helps the teacher.
The cat studies the bird.

💡 Singular pronoun → singular verb

👥
Plural
Multiple subjects take a plural verb
Keep the base form of the verb
We help the teacher.
The cats study the birds.

💡 Plural pronoun → base verb form

🔄 The Special "Be" Verb

The irregular "be" verb changes its form completely based on the subject.

📝 "Be" Verb Conjugation

Unlike regular verbs, "be" has special forms that change dramatically:

The book is heavy. (singular subject → is)
The tools are useful. (plural subject → are)

Remember: I am, you are, he/she/it is, we are, they are

🎯 Agreement Practice

Choose the correct verb form to complete each sentence!

studies

🧩 Tricky Cases to Master

These special situations can trip up even advanced learners!
🔍 Words Between Subject & Verb

Ignore extra words between the subject and verb:

The memory of my grandparents makes me happy.
Subject is "memory" (singular) → "makes"
🤝 Compound Subjects

With "and": Use plural verb

Tom and Jerry are friends.

With "or/nor": Use singular verb

Steak or seafood is fine.
❓ Indefinite Pronouns

"None" can be singular or plural (usually plural):

None of my bags ever arrive on time.
Think of it as "not one" or "not any"
📏 Proximity Rule

Verb agrees with the nearest noun:

One fourth of the classes were canceled.
25% of the class was canceled.
