Final answer:
Personal pronouns vary in form as subjective, objective, or possessive, depending on their function in a sentence. Understanding these forms helps in selecting the correct pronoun for grammatical correctness, exemplified by the proper use of 'I' and 'me' in different contexts.
Step-by-step explanation:
Understanding Personal Pronouns and Their Cases
Personal pronouns can take various forms depending on their function in a sentence, which can be subjective (acting as the subject), objective (acting as the object of a verb or preposition), or possessive (showing ownership).
Examples of Pronoun Usage
Subjective Case: I, we, you, he/she/it, they, who/whoever. For instance, in the sentence "He scored a goal," 'he' is the subject of the sentence.
Objective Case: me, us, you, him/her/it, them, whom/whomever. For example, "Laura gave him the baseball," where 'him' is the object of the verb 'gave'.
Possessive Case: my/mine, our/ours, your/yours, his/her/hers/its, their/theirs, whose. In "Those notes are his and mine," 'his' and 'mine' show ownership.
Correct Pronoun Selection
When selecting the correct pronoun, it is vital to consider the pronoun's function in the sentence to ensure proper grammar usage. For instance, "Jasmine and I ordered pizza for dinner. The pizza was delivered to Jasmine and me." In the first sentence, 'I' is the correct subjective case pronoun, while 'me' is the correct objective case pronoun in the second sentence.
