How can I express a countable noun together with its irregular plural form? For example, we may have the following sentence:
Find all critical point(s) of this function.
Since we do not know if the function has one or more critical points, we use the expression "point(s)".
What if the noun has an irregular plural form?
For example, should one say
Find all maximum/maxima of the function.
instead of using the parenthesis as we did in "point(s)"?
