How does one decide the correct verb and tense while describing a time or natural condition in the past? Take, for instance, the following sentence:
It was dark
Which of the following would be the most appropriate/natural translation and why?
My guess is it should be estar because it's a temporary situation and in the preterite form since it's one particular instance being described here (as against "It used to be dark"). Am I correct here?
Will the verb and tense change in any way if we said, "It was dark already," instead?
And lastly, what happens if we change the sentence into a progressive?
It was getting dark
