Why don't we use subjects such as" I " when using indirect object pronouns?

Question

When using ?ndirect object pronouns; why we don't use object such "I"? I'm confused!?

Answer 1

"I" is a subject pronoun.

English uses object pronouns for direct and indirect objects.

Singular

• 1st person: me
• 2nd person: you
• 3rd person: him, her, it

Plural

• 1st person: us
• 2nd person: you
• 3rd person: them

Answer 2

"I" is the subject pronoun -- the do-er of the action of the verb.

yo en espanol je en francés

an indirect object pronoun is the (usually) person who is affected by the action of the verb.

indirect object pronouns in English are in phrases like "to me" "from me" "for me" "for him" "to her" "to them" "to us"

Bad English grammar (which one hears fairly often unfortunately) is

Frank sent a letter to Mary and I. Take out the "Mary and " and

it sounds dumb to say " Frank set a letter to I."

Correct English is: "Frank sent a letter to me."

Frank sent a letter to Mary and me."
