There are 3 scenarios and I want to contrast the first with the second and the third. So on one side there is one single scenario and on the other side there is 2 scenarios. I like to use "former" and "latter" to refer to these two sides as in the following sentence:
The first case can not be compared with the second and the third cases, because the material used in the former is water-based while the one used in the latter is oil-based.
But then there seems to be an ambiguity in terms of plurality/singularity of what "latter" is referred to; it seems to me that "latter" has the connotation that there is just one scenario in the second side of the contrast. Is there any way to overcome this ambiguity? It seems to me that "latters" in plural is not a word.
