"Blue- bottle " and "Blue-bot" flies are a little technical - it requires knowledge about the difference between a common "house fly" and a "blue- bottle " fly. As a first guess, I would say that the text is from the South, but I could be wrong. The more common expression, in my opinion, would be "...and there was a dead fly on the sill." It seems you answered your own question Yes, I would say that a " bottle of milk" is a bottle that currently contains milk, while a "milk bottle " is a bottle that is intended to carry milk, whether it currently contains milk or not. Dear all, I know we can say "There is only a littke water in the bottle ." But I'm not sure if we can say "There is only little water in the bottle ." It sounds odd to me, though. Thanks! A water bottle is basically a bottle made for water and, water is the first liquid that was in it. If, after drinking the water, I fill this bottle with milk or wine, then it becomes a bottle of milk or wine but still remains a water bottle . Do I understand it well?
