Topic: Subject verb agreement
In the English language, subjects and verbs must always agree in number.
That means subjects and verbs must either both be singular,
or both be plural!
Singular subjects must have singular verbs while
plural subjects must have plural verbs
Tip: Singular means only one. Plural means more than one.
That’s why we say:
The dog is playing. ✅
Tip: ‘is’ and ‘are’, and ‘am’ are different forms of the verb ‘be’.
Which one you use depends on the subject!
Tip: ‘to be’ is an irregular verb, which is why the forms are
so different from each other.
They don’t follow a pattern.
Using ‘Is’, ‘Are’, or ‘Am’
Use ‘is’ with singular subjects.
He is proud.
Use ‘are’ with plural subjects.
1. We are proud.
2. The dogs are playing. ✅
Here are all of the ways to use ‘to be’:
I am happy.
You are happy.
He/She/It is happy.
We are happy.
They are happy.
Remember: You have to match the form of ‘be’ with
That’s called subject-verb agreement.
Tip: ‘agreement’ means not having a difference, or seeing
things the same way.
Subject-Verb Agreement in Regular Verbs
Great job learning about subject-agreement with
the irregular verb ‘be’.
Luckily, most verbs are not irregular.
So what pattern do regular verbs follow?
1. Regular verbs have a base form, like:
Then we add things like -s to the end to match the subject.
Using ‘Walk’ vs ‘Walks’
We don’t say:
We walks to the store. ❎
Instead we say:
We walk to the store. ✅
Jill walks to the store. ✅
So when do we add the -s?
The Rule to Remember
If the subject is singular or he, she , it, add -s to the base form.
1. Annie walks. She walks. He walks.
For all other subjects don’t add the -s.
2. I walk. They walk. You walk. We walk.
The children like fruit.
Children is a plural subject.
So we use the base form of the verb.
Let’s try another example.
Jeff likes fruit.
Jeff, the subject, is singular.
So we add -s to the base form of like.
