No, “though” is not a preposition. It is primarily a conjunction and can also function as an adverb.
Uses of “Though”:
- As a Conjunction (Introducing a Contrasting Clause)
- Though the restaurant was busy, the service was excellent.
- She enjoyed the meal, though it was a bit spicy.
- As an Adverb (Used Informally at the End of a Sentence for Contrast)
- The service was slow. The food was great, though.
- I didn’t expect much from the dish; it tasted good, though.
Why “Though” Is Not a Preposition
- Prepositions (e.g., in, on, under, about) show relationships between words.
- “Though” does not introduce a noun or pronoun and does not establish a spatial, temporal, or causal relationship—it connects clauses or modifies sentences, making it a conjunction or adverb.
Thus, “though” is a conjunction or adverb, not a preposition.
