indirect object
An indirect object is the receiver of the direct object. The assembled children are the ones who are receiving the information the meteorologist is telling. The subject of the sentence is who or what the sentence is about. The meteorologist is the subject of this sentence. He is doing the action. A predicate nominative renames the subject. It follows a linking verb. There is no linking verb in the sentence so predicate nominative is not an option. An appositive is a noun phrase that renames or describes the noun next to it. For example Sarah, my sister, is late. My sister is an appositive; it renames Sarah as my sister.
