It would be better if this thread is now closed.
Which type of conditional statement is it? I have never learnt such a conditional statement.
Suppose it was second conditional then, I have learnt, we use past verb in the if clause. e.g. If I were you, I would love her. But in the "It would be....is now closed", the present tense verb "is" has been used. So I am confused.
Could you help me with this?
The main clause or "apodosis" ("it would be better") is the main clause of a type 2 conditional.
The if-clause or "protasis" ("if this thread is now closed") is the if-clause of a type 1 conditional.
This kind of "mixed" conditional is common in spoken English and less formal kinds of written English (on webpages, in emails, etc.).
It can happen when a speaker begins his utterance in a conjectural or tentative frame of mind ("X would be better"), but then focuses on the immediate situation ("if Y is done").
