Here’s a question I received via e-mail:
My question is regarding the correct verb – singular or plural – in the following sentence:
Now what I want you to see is (or are) two things that deal with the subject.
I suggest a re-wording of the sentence to make this clearer to the reader:
Now I want you to see two things that deal with the subject.
The way you have it isn’t wrong, but it’s awkward. Writers want to avoid awkward construction or they risk distancing the reader. To answer your technical question: You need “are” because the objective clause is plural. The word “what” trips you up, as it tends to be thought of in the singular. In this instance, however, “what” you want = two things.
It’s usually best to use the simplest language possible in communicating, especially in giving instructions. That’s why I encourage you to re-word. Try: Look for two things that deal with the subject, Here are two things that deal with the subject, Let me point out two things that deal with the subject, or similar language.
Remember this crucial rule: Keep your sentences readable and flowing. If your reader stumbles and has to re-read a passage, she’s jarred out of the story.
Hope that helps!
