ellipsis - Singular/plural forms of objects with “respectively”
Which of the following two sentences is correct?
- A and B are the minimum and maximum value, respectively.
- A and B are the minimum and maximum values, respectively.
I tend to think that the first one is correct as it is a reduced version of the following sentence:
- A and B are the minimum value and the maximum value, respectively.
In other words, sentence 1 is sentence 3 with two ellipses.
This question was originally a part of that one. However, it had been left unaddressed there.
Answer
The second one is correct.
The descriptor of value in this context is the minimum and maximum. If you were saying this alone, would you say
minimum and maximum value
minimum and maximum values
Since there are two parts to the descriptor, minimum and maximum, value must get pluralized to values.
Another way you can look at this is by taking out the middle part of the sentence. In this case, which of the following is correct?
- A and B are the value
- A and B are the values
Again, the second one is clearly correct, because A and B are both being modified by values.
From a grammatical perspective, respectively is irrelevant here. While it may change the feel/mood of the sentence, it does not change its core meaning. By that, I mean you can get rid of it and the sentence will still mean roughly the same thing. Thus, the first part of the sentence must be treated independently.
