Question

Quizplus · Accepted Answer

A predicate adjective follows a linking verb and helps to explain the subject.
A linking verb is a verb that is not an action - it shows the relationship between two things in the sentence. Common linking verbs include forms of the verb "to be." (e.g. am, is, are, was, were, being, been)
In this example, "Very rare" modifies the subject "That first-edition book" and is linked by the verb "is."
That first-edition book is very rare; you should buy it before someone else does.
