could you please give me an example of the usage of the simple past tense indicating future time in English? I've got two but am not sure which one is correct or neither.
1 he said he would leave for tomorrow.
2 he would leave for tomorrow.
is there any difference between the two woulds in question in relation to time reference?
could you give me one more exmaple?
1 He said he would leave tomorrow.
2 He would leave tomorrow.
Let's begin with the second sentence. Here "would" is not the same as "will." In fact, the sentence is ambiguous and is not something you would ordinarily hear. It needs something to tell us whether it is a case of the conditional ("If we gave him the money he would leave tomorrow") or something else (as in the first sentence.)
The first sentence, as well, implies to me a certain ambiguity. If you say, "He said he will leave tomorrow," you are clearly saying that his action is in the future. "He said he would leave tomorrow," on the other hand, suggests to me that he may or may not be going on that day or at all. Ordinarily you would use "would" to imply less certainty.
Having said that, you could probably use "would" here and people would understand it as simple future, as you suggest.
It is a subtle thing. Perhaps others can explain it better.
