No, “yet” is not a preposition. It is primarily an adverb and can also function as a conjunction in some cases.
Uses of “Yet”:
- As an Adverb (Indicating time, contrast, or degree)
- The restaurant hasn’t opened yet. (Time)
- The menu is simple, yet elegant. (Contrast)
- The new POS system is even better yet. (Degree)
- As a Conjunction (Connecting contrasting clauses, similar to “but”)
- She was full, yet she ordered dessert.
- The service was slow, yet the food was amazing.
Why “Yet” Is Not a Preposition
- Prepositions (e.g., in, on, under, about) show relationships between words and require an object.
- “Yet” does not function this way; instead, it modifies verbs, adjectives, or entire clauses, making it an adverb or conjunction.
Thus, “yet” is not a preposition; it is mainly an adverb or conjunction.
