What is the predicate noun in sentence The fable teaches importance of hard work?

The predicate noun in the sentence "The fable teaches the importance of hard work" is importance.

Here's why:

* Predicate Noun: A predicate noun renames or identifies the subject of the sentence. It follows a linking verb (in this case, "teaches").

* Subject: The subject of the sentence is "The fable".

* Linking Verb: The linking verb "teaches" connects the subject to the predicate noun.

Therefore, "importance" acts as the predicate noun, renaming or identifying the subject "The fable" as something that embodies "importance".
