What Is Subject-Verb Agreement?
Subject-verb agreement just means using the right version of the verb to agree with the subject. For example:
If you use the term "verb conjugation," your mates will probably think you're bit of brainbox, but it just means "how verbs change to agree with their subjects."
It's really simple. If you're a native English speaker, you'll naturally ensure your verbs agree with their subjects (i.e., conjugate correctly). Here's an example:
|Subject||Conjugation of the Verb|
|He / She / It||is|
That was the verb to be. Most other verbs are even easier:
|Subject||Conjugation of the Verb|
|You|| play |
|He / She / It||plays|
|We|| play |
|You|| play |
|They|| play |
It is a simple concept, but, sometimes, it's difficult to know whether your subject is singular or plural. In other words, should you be using a singular verb (like is and plays) or should you be using a plural one (like are and play)? Below is a summary of the areas which cause the most problems:
Someone and Anyone Take Singular Verbs
The indefinite pronouns
anyone, each, everyone, no one, nobody, and someone are singular. For example:
That all seems pretty straightforward. However, if you have to use a possessive adjective (e.g., his, her) in the same sentence, problems start to arise. Look at this example:
- No one knows what he can do till he tries. (Publilius Syrus, circa 100 BC)
- I hope that while so many people are out smelling the flowers, someone is taking the time to plant some. (Herbert Rappaport)
- The supreme irony of life is that hardly anyone gets out of it alive. (Robert Heinlein, 1907-1988)
- Nobody is ever met at the airport when beginning a new adventure. (Elizabeth Warnock Fernea)
What if the person isn't male? The English language doesn't handle this very well. This is covered more in the Beware section on the right.
- If anyone goes to a psychiatrist, he ought to have his head examined.
All and Some Can Take a Singular or a Plural Verb
The indefinite pronouns all, any, more, most, and some are singular when they refer to something singular (i.e., a non-countable noun) but plural when they refer to something plural (i.e., a countable noun).
- All of the bread has been stolen.
- All of the biscuits have been stolen.
- My theory is that all of Scottish cuisine is based on a dare. (Mike Myers)
- Some of the worst mistakes of my life have been haircuts. (Jim Morrison, 1943-1971)
Number Of Takes a Plural Verb...Most of the Time
If it helps, you can think of number as following the same rules as all and some (see above). Therefore, the term a number of will nearly always be plural because the object of the preposition of (i.e., the word that follows it) will be plural. For example:
Beware though, because number can be a singular noun referring to an arithmetical value.
- A number of men were strongly opposed to the changes.
- Lee, a number of cakes have been stolen from the buffet.
- The number of women was sixty-four.
- The number of women were sixty-four.
Terms Like Half Of, the Majority Of, and a Percentage Of Can Be Singular or Plural
Expressions such as half of, a part of, a percentage of, a proportion of , and a majority of are singular when they refer to something singular but plural when they refer to something plural.
- Democracy is the recurrent suspicion that more than half of the people are right more than half the time. (E. B. White, 1899-1985)
- Half of the world knows not how the other half lives. (George Herbert, 1593-1633)
- Ninety percent of the politicians give the other ten percent a bad reputation. (Henry Kissinger)
- My guess is that well over 80 percent of the human race goes without having a single original thought. (H. L. Mencken, 1880-1956)
None Can Take a Singular or Plural Verb
The indefinite pronoun none can be singular or plural. However, be aware that treating none as plural might irk some of your readers as many people believe none can only be singular. For example:
Here's a tip: If your none translates best as not one of, then treat it as singular. If it translates best as not any of, then treat it as plural. If this doesn't work for your example, then try to treat it as singular. If, however, that just sounds wrong, be brave and go for plural.
- None of the team is ready.
- None of the team are ready.
Also, keep an eye out for the his/her/their issue. Look at this example:
Try to avoid mixing singular verbs and plural possessive pronouns. As covered in the Beware section on the right, the English language doesn't cope with this very well, but as you often have the choice whether to treat none as singular or plural, you can avoid this failing. For example, write this instead:
- None of the team has polished their boots.
- None of the team have polished their boots.
The Words after As Well As Are Not Part of the Subject
The words which follow terms like as well as, along with, and together with are not part of the subject. They do not compound the subject like and does. For example:
- The king along with his sons is visiting tomorrow.
- The king and his sons are visiting tomorrow.
Either and Neither Are Singular
The pronouns either and neither take singular verbs. This often causes confusion because they naturally refer to two things. For example:
- I'm not keen on beef or lamb, but either is preferable to tofu.
- Neither of the sisters is eligible to attend.
Or Does Not Conjoin
Unlike and, the conjunctions or and nor do not conjoin. For example:
The pairings either/or and neither/nor demand a singular verb when both elements (shown in blue below) are singular, but a plural verb when one of them is plural. For example:
- The king or his daughter is visiting tomorrow.
- The king and his daughter are visiting tomorrow.
- Neither the king nor his daughter are visiting tomorrow. (should be is)
- It's very tasty as it is. Neither salt nor pepper is required.
Let's call that the "Mathematical Rule."
- Either the king or the queen is coming to present the awards.
(The elements (shown in blue) are both singular. Therefore, the verb is singular.)
- Neither cakes nor chocolate are going to give you the nutrients you need.
(Here, one of the elements (cakes) is plural. Therefore, the verb is plural.)
You should also be aware that there is a well-followed rule called the Proximity Rule, which offers different guidance. Under the Proximity Rule, the verb is determined by the nearest element to the verb. For example:
You can follow the "Mathematical Rule" or the Proximity Rule. You should adopt whatever convention those around you do. If you can't find such guidance, then pick one of the conventions and be consistent.
- Neither cakes nor chocolate is going to give you the nutrients you need.
(Here, the nearest element (chocolate) is singular. Therefore, the verb is singular. Under the "Mathematical Rule," this would be wrong as cakes is plural.)
Here's a good tip: often, you can edit your words so you adhere to both rules. For example:
- Neither chocolate nor cakes are going to give you the nutrients you need. ("Mathematical Rule") (Proximity Rule)
Beware Modifiers Getting between the Subject and the Verb
Sometimes modifiers (shown in blue) will get between a subject and its verb, but you must not let these words interfere with the subject-verb agreement.
- A crate of sardines is more expensive than I thought.
- Simon, who is the oldest of the four brothers and who, just as he did before last year's contest, has been suffering back spasms, is expected to take the first leg.
- A container of nuts and bolts were found in the cellar.
(Container is singular. It should be was.)
A List of Words That Cause Confusion
The words listed below often cause singular/plural confusion.
|Word||Singular or Plural?|
(even though it is the plural of agendum)
Read more about agenda being singular.
(Unlike data and agendum, criteria has retained its plural status because the singular criterion is still in common usage.)
Read more about criteria being plural.
(even though it is the plural of datum)
Read more about data being singular.
(Note: Pair of glasses is singular.)
|Media||Singular or Plural|
(Treat media like a collective noun as opposed to the plural of medium.)
(Note: Pair of pliers is singular.)
(Note: Pair of scissors is singular.)
(Note: Pair of underpants is singular.)
Collective Nouns Can be Singular or Plural
A collective noun is a word that represents a group (e.g., board, team, jury). A collective noun can be singular or plural depending on the sense of the sentence. Look at these two examples.
Often, it's difficult to make a decision on whether to opt for singular or plural. A good trick is to precede your collective noun with words like members of…, forcing you to go plural. For example:
- The jury is late returning to the courtroom.
(singular – considered as one unit)
- The jury are all wearing different coloured shirts.
(plural – considered as individuals)
- The members of the jury are late returning to the courtroom.
The Term More Than One Is Singular!
The expression more than one takes a singular verb. For example:
- More than one person was involved in this robbery.
- More than one swallow does a summer make, doesn't it?
- All I can say is that more than one of you have promised to return after the break.
The Positive Element Governs the Verb
When a subject is made up of a positive element and a negative element, the positive one governs the verb. For example:
- The CEO not the board members makes the final decision.
(Positive element: CEO / Negative element: board members)
- The kitchen has confirmed that the fish not the prawns was responsible for the vomiting outbreak.
(Positive element: fish / Negative element: prawns)
