Meaning and use

Formal conditional inversion can replace if with had, were, or should before the subject. Had marks an unreal past condition; were to often marks a hypothetical future; should makes a condition tentative. Negatives place not after the subject. Not every if-clause can be inverted by moving any verb.

Instead of	Use	Why
Had not I checked, I would have missed it.	Had I not checked, I would have missed it.	In a full negative inverted conditional, not follows the subject.
Were she ask, I would agree.	Were she to ask, I would agree.	Use were + subject + to-infinitive in this hypothetical pattern.
