Have you finished with this?
No, I'm still drinking it.
Macmilian Dictionary says that finish with means "you have stopped using it". In this sentence, I think "Have you finished this?" works. Another example is the following:
I've finished my meal.
I've finished with my meal.
Could you explain the difference?
How about this sentence?
I've finished using my camera.
Can I also say, "I've finished with my camera"?
I've never used finish with. That's why I'm not sure how to use it.
Could you possibly give me some examples using finish with?
