I vs. Me
Have you ever asked yourself, "When should I use, 'I or me?'"
Both of these words are pronouns; from their definitions below, they look pretty similar. Take a look for yourself.
pronoun[first person singular] used by a speaker to refer to himself or herself: accept me for what I am.
pronoun[first person singular] used by a speaker to refer to himself or herself as the object of a verb or preposition: do you understand me? | wait for me!
There you go, 'Me' is used as an object of a verb or preposition. One thing not noted is that 'I' is a subject pronoun.
So, a quick question you can ask yourself is, "Is this sentence about me doing something, or is it about someone doing something to/for me?"
The subject in a sentence is the person or thing performing the action.
The object in a sentence receives the action of a verb. Identify the object by finding the verb and then asking “what” or “whom.” See a few more rules here.
Let's take a look at two examples to illustrate this point.
I went to the store and bought three new books to read over summer break.
He went to the store and bought me three new books to read over summer break.
There are a number of other uses, but let's explore those at a later time. Till then, thank you for reading.
