In a scientific paper I submitted, a reviewer suggested that I change the sentence
The operation just substitutes "(m, l)" with "m" on both the sender and the receiver side.
The operation just substitutes "(m, l)" with "m" on both the sender and the receiver sides.
by changing the last word from singular to plural.
There is only one sender side and only one receiver side, so my intuition tells me to use the former version, since
- one would clearly write "...both the sender side and the receiver side" and
- I'd also write "The green and the blue box are standing on the table" (instead of "boxes").
However, I failed to find a grammatical rule for this, and English is not my main language. Is the reviewer right? And why?
