While analyzing essays, I often get confused between whether a word is a predicate adjective of an action verb.
I found the definition of a predicate adjective to be "An adjective used in the predicate, especially with a copulative verb and attributive to the subject."
I also found the definition of an action verb to be "A verb that expresses something that a person, animal, object, or process in nature can do."
However, even with these definitions, I am confused about how to tell these apart.
For example, the sentence "A list of objects was written." In this sentence, what would the word "written" function as? Would the "was" be a linking verb and the word "written" a predicate adjective? Or would "was" be a helping verb and the "written" be an action verb?
