SUBJECT AND VERB AGREEMENT

How to make verbs agree with their subjects?

1. What are verbs and subjects?

Verbs are what we called action words

example:

run, do, walk, buy, shop, sing
Subjects are the person or thing who are doing the action of the verb.

example:

I walk; The horse runs; Krishna sings Korean songs; They watch Transformers.

The subject of a sentence can be singular (one) or plural (many).

example:  

The shirt is big. (singular)
The shirts are big. (plural)

2. What is verb-subject agreement?

The subject and verb must agree in number: both must be singular, or both must be plural.

example:  

The elevator (singular subject) was (verb) full.
The elevators (plural subject) were (verb) full.
In these sentences each of the verbs agrees with its subject. The correct verb form has been used.

The verb must always agree with its subject.

Single subject = single verb
Plural subject = plural verb.


3. How does this work?

In regular verbs:
                                                       Singular                            Plural
First person                           I like strawberries.         We like strawberries.
Second person                   You like strawberries.       You like strawberries.
Third person             he / she / it likes strawberries.  They like strawberries.

Rhodge likes to walk to work.(correct) 
Rhodge like to walk to work.(incorrect)
They like dancing. (correct) 
They likes dancing. (incorrect)

Note: 's' is added to the third person singular. This is the way most regular verbs in the present tense work.
