Question

But for your interference everything would have gone smoothly on.(use if)​

Answer 1

Answer:

Does 'but for' mean:

'If we had X (but we didn't), Y would have been the consequence'?

Or can it also mean; because we had X, as a result Y happened?

Some different examples of but for:

(Case 1)

But for a cup coffee, it was to be a productive day of writing. Unfortunately, I'd run out, and spent the day craving.

(Case 2)

But for the glass of wine I had dinner, the house work didn't get done.

(Case 3)

But for the glass of wine I had for dinner, I would have got the house work done
