No, “each” is not a preposition. It functions as a determiner, pronoun, or adjective, depending on its usage in a sentence.
Uses of “Each”:
- As a Determiner (Modifies a noun to indicate individuality within a group)
- Each customer received a menu.
- Each dish is made fresh to order.
- As a Pronoun (Replaces a noun while emphasizing individuality)
- Each of them ordered a different meal.
- The servers greeted the guests one by one, speaking to each.
- As an Adjective (Describing a noun to emphasize individuality)
- They checked each order before serving.
- Each table has a unique design.
Why “Each” Is Not a Preposition
- Prepositions (e.g., in, on, under, about) show relationships between words.
- “Each” does not establish a relationship between a noun/pronoun and another word; instead, it functions as a determiner, pronoun, or adjective to indicate individuality.
Thus, “each” is not a preposition.
