The quality or state of being humped, hunchbacked, or having a pronounced curve.
From Latin 'gibbus' (hump) plus the English noun-forming suffix '-osity,' creating an abstract noun for the condition of having a gibbus or hump.
This ultra-rare word is the noun form of 'gibberose'—it's the kind of medical or anatomical term a Victorian doctor might use in a journal, but it's so archaic that even modern dictionaries barely recognize it.
