Many people make mistakes with subject and object pronouns. Do you? Let's see!
Do you know which of the following sentences is correct? Do you know why?
The question here is whether to use the pronoun I or the pronoun me after a preposition (to).
In order to understand the answer, we need to learn a little bit about prepositions and pronouns. Here we go!
A prepositional phrase is a group of words that begins with a preposition and ends with a noun or a pronoun. Here are a few examples of prepositional phrases.
with butter, during lunch, from Margaret
The noun or pronoun at the end of the phrase has a fancy name. It's called the object of the preposition.
The job of a preposition is to show how the object of the preposition relates to other words in the sentence. So, in order to do its job, every preposition needs an object of the preposition.
Pronouns are words that take the place of nouns. Different pronouns perform different jobs in our sentences.
Some pronouns are used as subjects (I, he, she...), and some pronouns are used as objects (me, him, her...).
You can't mix them up. Unless you are Tarzan, you wouldn't say, "Me want water."
The word me sounds wrong because it's an object pronoun trying to do the job of a subject pronoun. You would say, "I want water."
I is a subject pronoun, and it is the subject of the sentence.
Remember that we're talking about objects of the preposition.
Prepositions need objects (nouns or pronouns), and their objects need to be in the objective form. Since I is a subject pronoun, it can't be the object of a preposition.
That is why the following sentence is correct.
