Thank you for your patience over the last 15 weeks whilst we build this road
Can I replace the over by during or in and if I can, is it making any difference then?
The previous question in this regard didn't get a thorough explanation about over and during being used with a period of time. Some indicated when during are used with a period of time, it has connotation that thing happened intermittently, but in fact I can find many instances contradict this viewpoint, saying, wages have fallen by more than twenty percent during the past two months...and interesting thing is we have a analogous sentence in which over is used, the number of attacks on the capital had gone down over the past week...
My goal is to make the difference between them clearer rather than ambiguous results got in that post.
