Subject-verb agreement

 
In this topic, you will learn the correct way to match the singular or plural subject with the verbs. 
 
2.1  Singular Subjects
 
  A singular subject takes a singular verb.  
  Singular subject + Singular verb  
     

 

Note: Indefinite pronouns such as someone, everybody, no one, anyone are considered as singular subjects. 
 
Examples:
 
That debater usually presents interesting arguments.
Singular subject Singular verb  
 
The traffic light turns red every few minutes.
Singular subject Singular verb  
 
Someone has stepped on the grass. 
Singular subject Singular verb  
 
Note: There is an addition of '-s' at the end of the verb if the subject is in the singular form. (Eg: eats, drinks, runs, reads)
 
2.2  Plural Subjects
 
  A plural subject takes a plural verb.   
  Plural subject + Plural verb  
     

 

Examples:
 
They regularly conduct seminars on AIDS to educate people about the disease.
Plural subject Plural verb  
 
There  are three types  of mangoes there. 
  Plural verb Plural subject  
 
Danial and Henry attend Sunday school together. 
Plural subject Plural verb  
 

Note: No '-s' is added at the end of the verb if the subject is in the plural form. (Eg: eat, drink, run, read)

 
2.3  Linking Verbs
 
  Linking verbs  
  Verbs that link the subject to the complement in a sentence.  
     
 
Example:
 
They were at the netball court the whole day. 
Subject They
Linking verb were
Complement at the netball court the whole day. 

 

  Three types of linking verbs  
 
(a)  'be' verb
(b) 'has' and 'have'
(c) action verbs (Eg: take)
