Making Subjects & Verbs Agree

Many writers have problems with subject-verb agreement (having singular nouns with singular verbs, and plural nouns with plural verbs). Sometimes, these slip-ups are glaringly obvious:
 
ex. Bob are a college student.
 
In many sentences, however, word groups intervene between the subject and verb:
 
ex. Today, writing papers with word processors are much easier. (what's the problem here?)
 
The easiest way to check your subject-verb agreement is to take out any word groups (usually subject modifiers) between the subject and verb:
 
ex. Today, writing is much easier.
Changing the sentence in this manner, however, changes the meaning. Reorganizing the sentence clears up the problem while retaining meaning: ex. Word processors make writing papers much easier.
When you edit, look for these common trouble spots:

Make the verb agree with its subject, not with the words that come between the subject and verb:

ex. The woman who made those cakes is our next-door neighbor. (woman is, not cakes are)


With compound subjects that are connected by "and", "or", "nor", "either . . . or", "neither . . . nor":

Use a plural verb for subjects connected by "and":
 
ex. The dog and cat seem to be good friends.

Use a singular verb for subjects joined by "or" or "nor":
 
ex. Either John or Karen is available to answer your questions this afternoon.
 
When a singular subject and a plural subject are joined by "or", "nor", or "neither . . . nor", the verb agrees with the nearer subject:
 
ex. Neither the zoo keeper nor the police were able to find the missing boa constrictor.
 
With collective nouns when the verb depends upon the nature of the subject:
    ex. A number of companies are hiring Y2K specialists. (Here, a plural verb because the companies are not acting as one body but rather as a number of individuals).
     
    ex. The consortium of companies is hiring more Y2K specialists. (Here, "consortium of companies" implies that the companies are acting together as a single entity).
 

 


The following examples include improper subject-verb agreement. Change them so that the verb agrees with the subject.

High levels of radiation causes cancer in laboratory rats.



The Cabinet is inept; that group of imbeciles are ruining the country.



Neither the parents nor their son were at home yesterday.
