Final answer:
Predicates contain information about how the action in a sentence is done, often through descriptive terms or adverbials which add clarity and detail to the statement.
Step-by-step explanation:
The information contained in a predicate that tells us how the action of the predicate is done consists of descriptors and may often be adverbials which clarify the manner, time, or place of the action. In sentences like "The bird sings joyfully", "joyfully" is a part of the predicate that describes how the bird sings.
Predicates, as part of sentences, not only include verbs which express actions or state of beings but also provide description or characterization of the subject. The predicate can include descriptive terms like "yellow," "six feet tall," or informative phrases like "faster than a speeding bullet." Therefore, understanding predicates enhances clarity in our language, aiding in the removal of ambiguity and vagueness.
