Grammar Rule in 30 Seconds
Replace 'If' with auxiliary verbs like 'Had' or 'Were' to sound more formal and sophisticated in your writing.
- For Type 2, start with 'Were': 'Were I you, I would go.'
- For Type 3, start with 'Had': 'Had I known, I would have come.'
- Never use 'If' when you use inversion.

“Were I rich, I would travel.”

Type 3 Inversion
Hypothetical past situations.
