<p>“The plays that they didn’t make in the football game WERE/WAS the DIFFERENCE(S) between winning and losing.”</p>
<p>Can you have something plural, with a plural verb, and then have the predicate nominative be singular?</p>
<p>It depends on whether “plays” can be properly classified as singular or not.</p>
<p>I would like to say “The plays that they didn’t make in the football game were the difference between winning and losing” but I don’t know.</p>
<p>Just shorten the sentence to make it easier “The plays were the difference between winning and losing”. This statement seems to sound correct and seems to be the correct answer.</p>
<p>yea i am pretty sure it is “were”</p>
<p>So basically the subject can be plural and the predicate nominative can be singular. I’m trying to get all of these rules down, and I’m having some problems with idioms. Any good site to memorize a lot of them?</p>
