What “Mi” means
Mi is the first-person pronoun and covers I, me and my, because Patois pronouns don't change form. "Mi hungry" is "I'm hungry", "gi mi" is "give me" and "mi madda" is "my mother". "A mi" puts the focus on me: "A mi dat" means "That's me."
Examples
Mi hungry
I'm hungry
Mi nuh know
I don't know
Mi madda a call yuh
My mother is calling you.
How to use it
The everyday word for I, me and my in all situations. For emphatic possession, use "fi mi" (mine).
