The quality or state of being dropsical; the condition of having or relating to dropsy.
From 'dropsical' with the noun-forming suffix '-ness,' creating an abstract noun for the quality or condition.
The '-ness' suffix is English's workhorse for turning adjectives into abstract nouns—'dropsicalness' captures not just the symptom but the overall state of suffering from the condition, though it's rarely used today.
