* Predicate Nominative: This is a noun or pronoun that renames the subject. It follows a linking verb (like "is," "are," "was," "were," "seems," "becomes," etc.).
* Example: "The insect is a grasshopper." Here, "grasshopper" renames the subject "insect."
* Adjective: This describes a noun or pronoun. It can modify the subject, the object, or another adjective.
* Example: "The grasshopper jumped." Here, "grasshopper" describes the subject "insect."
To determine whether "grasshopper" is a predicate nominative or adjective, look at the sentence and identify the verb and what it's connecting.
