NOT" in general and possible conditions only.Other structures  As long as, providing (or provided that) and on condition: these expressions mean only if and can be used with the same verb forms as conditional sentences: In Spain you can drive a car as long as you are 18  Inversion of subject and verb: this structure is very common in formal English in conditional sentences with should and the past perfect. When inversion is used, we omit if: Had I known about the transport strike, I would have taken my car. Should you meet Sheila, tell her the meeting has been postponed.
