===Interrogative pronouns===
The interrogative pronouns ''who'' and ''what'' generally take singular agreement,<ref name=Huddleston>{{Cite book|pages=505–506|last1=Huddleston |first1=Rodney |author-link1=Rodney Huddleston|last2= Pullum |first2= Geoffrey |author-link2=Geoffrey Pullum|title=The Cambridge Grammar of the English Language |year=2002 |publisher=Cambridge University Press |isbn=0-521-43146-8}}</ref> e.g.
* ''Who works there?''
In some cases, a plural verb can be used when the answer is expected to be plural<ref name=Huddleston/>
* ''What have big ears and trunks?''
When followed by a plural predicative complement, a plural verb must be used:<ref name=Huddleston/>
* ''What are the main reasons?''
not
* *''What is the main reasons?''
Following ''which'', a singular verb suggests a singular answer, and a plural verb suggests a plural answer:<ref name=Huddleston/>
* ''Which of these answers is correct?'' (single choice)
* ''Which of these answers are correct?'' (multiple choice)
<!--Relative pronouns, however, commonly take plural agreement (e.g., ''I saw the workers who were leaving.''). Not the topic of this section-->

When asking ''How many?'', plural is standard (e.g. ''How many bananas?'' not *''How many banana?''), even if the expected answer is only one.
