When one uses simple past tense for some action, does it imply that the action is complete?
For instance, when you say “I wrote my article yesterday,” does this imply that at this moment you have a finished article or not? So it’s
I wrote a bit of my article yesterday, but I still have to finish it.
I started and finished writing my article yesterday and now I have a finished work, so I can publish it.
What about present perfect? Does it imply completeness? If you say “I have watched this film,” does this mean that you have actually watched it from start to end?
If both these tenses imply that the action was completed, do I have to use past continuous to emphasize the incompleteness of action? For instance, “I was watching this film,” so that the implied meaning is that I started watching it, but it’s not certain that I finished it.
