Final answer:
An object in a sentence is a noun or pronoun affected by the action of a verb or a preposition. Examples include 'ball' in the sentence 'Robert dropped the ball' and 'him' or 'me' in sentences with actions like 'Laura gave him the baseball' or 'The pizza was delivered to Jasmine and me.'
Step-by-step explanation:
An object in a sentence is a noun or pronoun that is affected by the action of a verb or a preposition. In other words, it receives the action performed by the subject of the sentence. For example, in the sentence 'Robert dropped the ball during the final seconds of the game', 'ball' is the object because it is what Robert (the subject) dropped (the action).
Pronouns must agree with their antecedents in grammatical function. So, in sentences like 'Laura gave him the baseball,' 'him' is a pronoun in the objective case because it is receiving the action of the verb 'gave.' Similarly, in the sentence 'The pizza was delivered to Jasmine and me', 'me' is used correctly as an object of the preposition.
