I’d like to understand the nuances in meaning between many and many of. Unfortunately, the references that I’ve found only explain the difference in grammar usage.
Here are two sentences from a grammar book that touches on that difference but does not explain it fully.
Many tiles in the bathroom are getting discolored from water stains.
According to the author: “Many tiles means more than a few but less than most”. I understand it could any number between 10-49% of the tiles. Would you understand it the same way?
Many of the tiles in the bathroom are getting discolored from water stains.
According to the author: “Many of the tiles implies that a significant number of the tiles have become discolored and that something may have to be done about it”.
What percentage of the tiles should be understood by the significant number? Is it still less than 50% but more than just "many"? Or is it perhaps between 50-70%? Is the difference between many and many of just about the number of the tiles or that something needs to be done about it also plays an important role here?
