No, “my” is not a preposition. It is a possessive pronoun (or possessive determiner).
Function of “My” as a Possessive Determiner:
- Indicates Possession or Ownership
- My restaurant is doing well this season.
- She forgot my order.
- Used Before a Noun (Modifies a noun by showing ownership)
- I updated my POS system.
- My customers love the new menu.
Why “My” Is Not a Preposition
- Prepositions (e.g., in, on, under, about) show relationships between words.
- “My” does not establish relationships; it indicates possession, making it a possessive pronoun/determiner.
Thus, “my” is a possessive determiner, not a preposition.
