In the English language, pronouns are used to replace nouns in sentences. This is in order to avoid redundancy. There are many kinds of pronouns meant for various uses. Sometimes, we get overwhelmed by the sheer amount of pronouns that we mix them all up.
Take the pronouns: I, me, and myself. They all replace the first-person singular noun, which is the speaker. Despite that, we still misuse them. Just look at the examples below.
Me and May organized the surprise party.
Myself and May organized the surprise party.
For some odd reason, all of them sound correct, but they aren’t.
May and I organized the surprise party.
