Here is a worksheet on the use of every, which is an adjective, but which readily joins with words like body and one to give us nouns like everybody and everyone. These are singular nouns, so they take singular verb forms. That’s the gist of this worksheet–but there is a small excursus on the use of their with these nouns in the interest of avoiding gendered pronouns, and therefore sexism in language.
The worksheet consists of 10 modified cloze exercises, which you may modify further, as this is an open source document formatted in Microsoft Word. Which, like all of the documents under the header of Common Errors in English Usage, are informed by Paul Brians’ excellent book of the same name, which he has posted on the Washington State University website.
