Question
Is it correct to say "One dog and one cat were lying on the sofa"? — Valerie, United States
Answer

When two or more nouns are joined by the word "and" it is called a compound subject. Even when each noun is singular, the whole phrase takes a plural verb. Below are some examples of this.

  • Her book and her purse are sitting on the table.
  • An apple and an orange were left in the cafeteria.
  • Cheryl and Frank are traveling to Japan next month.

 

When a compound subject is joined by the word "or" an English teacher will tell you that the verb should agree with the noun closest to it. When each noun in a compound subject with "or" is singular, the verb should be singular too. These rules are followed in formal writing, but he choice between a singular and plural verb often varies in actual use. Below are some examples of this.

  • Either John or his sisters are calling us tonight.
  • The house key or the car key is missing from his key ring.
  • Either those books or that box are good enough to use as a table for now.
  • One or more of us is going to have to move over to make room.
  • He knows a banana or an orange is waiting for him in his lunchbox.
  • The girls or their mother have to come with us to pick out a gift.
