The best way to reword the parenthetical plural “diagnosis(es) and remedy(s)”

grammatical-numberparenthetical-pluralphrase-usagephrasing

What is the best way to word the following sentence?

A diagnosis(es) and remedy(s) remain elusive as we continue to seek help from various medical professionals.

Since diagnosis ends in -is, should the parenthetical plural "diagnosis(es)" be something else? I could reword but it sounds a little…wordy. Plus, if not also spelled out, "remedy(s)" then seems inconsistent:

A diagnosis (or diagnoses) and remedy(s) remain elusive as we continue to seek help from various medical professionals.

Best Answer

In the sentences you give, a parenthetical plural is completely unnecessary.

Diagnoses and remedies remain elusive as we continue to seek help from various medical professionals.

is perfectly good grammar, and makes it clear that all diagnoses and remedies are elusive - i.e. no single diagnosis or remedy has been found.

It would also be correct to use the singular:

A diagnosis and a remedy remain elusive as we continue to seek help from various medical professionals.

This means exactly the same thing.

Attempting to try to cover both the singular and plural is unnecessary.
