No, “will” is not a preposition. It is a modal verb.
Function of “Will” as a Modal Verb:
- Expressing Future Tense
- The restaurant will open at 10 AM tomorrow.
- She will upgrade the POS system next month.
- Expressing Willingness or Intent
- I will help you set up the new menu.
- The manager will handle the issue.
- Expressing Probability or Expectation
- This will improve efficiency.
- The customers will love the new menu.
Why “Will” Is Not a Preposition
- Prepositions (e.g., in, on, under, about) show relationships between words.
- “Will” does not establish relationships; it is a modal verb that helps express future actions or intentions.
Thus, “will” is a verb, not a preposition.
