Quantity expressions can be troublesome when it comes to subject-verb agreement. The rules below govern quantity expressions with both singular and plural verbs.
- When a quantity word is followed by a prepositional phrase, the verb usually agrees with the quantity word.
One of the presidential candidates is in town today.
Three of my classes were cancelled yesterday!
- Some expressions of quantity can take either a singular or a plural verb depending on whether the noun in the prepositional phrase is singular or plural.
|All of the…||All of the restaurant was full.||All of the restaurants were full.|
|A lot of…||A lot of the money was torn.||A lot of the bills were torn.|
|Some of the…||Some of the pizza has been eaten.||Some of the pizzas have been eaten.|
|One-half (third, quarter) of the…||One-third of the population is going to vote.||One-third of the people are going to vote.|
- The quantity word none takes a singular verb. Remember that none means “not one” (and “one” is singular).
I looked at all the paintings. None is interesting to me.
None of the paintings is interesting to me. (formal)
- In spoken English, most people use a plural verb when a plural noun follows none. Never use a plural verb with none in formal academic writing.
Informal use only: None of the paintings are interesting to me.
- When you use the following quantity words alone as subjects, without objects of prepositions after them, they take the verbs indicated below.
|One is / makes||Both are / need|
|A little is / falls||A few are / fall|
|Each is / needs|
|Every is / has|
