No, “it” is not a preposition. It is a pronoun.
Function of “It” as a Pronoun:
- Used as a Subject or Object Pronoun
- The restaurant has a new menu. It looks great! (Subject pronoun)
- I tried the special dish and loved it. (Object pronoun)
- Used as a Dummy Subject (for weather, time, or general statements)
- It is raining outside.
- It was a busy day at the restaurant.
Why “It” Is Not a Preposition
- Prepositions (e.g., in, on, under, about) show relationships between words in a sentence.
- “It” does not establish relationships; instead, it replaces a noun.
Thus, “it” is a pronoun, not a preposition.
