How do I express the thought that the occurrence of some event results in the occurrence of another before it.. in other words, that if an event were to happen, some other event would happen before it?
I would say:
If A were to happen, B would happen before it.
If A would happen, B would happen.
If A happened, B would have happened.
In the second example, I used would because I read this on Grammarly:
An if- or when-clause (often used to form conditional sentences) generally does not contain “will,” which is the simple future tense of the verb “to be.” One exception is when the action in the if- or when-clause takes place after that in the main clause. For example, consider the following sentence: If aspirin will ease my headache, I will take a couple tonight instead of this horrible medicine.
and this from wikipedia:
Also, in cases where the event of the if-clause follows that of the main clause, use of would in the if-clause is standard usage (this is similar to the aspirin example given above for will):
If it would make Bill happy, I would give him the money.
And from my understanding, I think that the last example only describes or talks about the present, it doesn't say anything about the future. The result clause concerns the past of the moment of speaking, no more, and the condition concerns one case or instance whose result took place already in the past.
Do the examples express that thought? Also, does the following express that thought?:
If A will happen, B will happen before it.
