subject and object pronouns
Rishi and (I,me) have always shared an intimate relationship over the years.
Answer:
I
Explanation:
In English language, a subject can be defined as the person, thing, idea or place that performs an action.
On the other hand, an object refers to the person, thing, idea or place that receives an action performed by the subject.
Also, a direct object is the specific thing a subject acts upon and as such it answers the question of what, whom or who.
A pronoun is one of the parts of speech and it can be defined as a word that replaces a noun in a sentence. Some examples of a pronoun are he, she, you, I, who, it, them, ours, etc.
Therefore, Rishi and I have always shared an intimate relationship over the years. Rishi is the subject while I is the object pronoun.
