fibrosis

the term fibrosis is a modern medical compound built from classical roots. its first element, 'fibr-', derives from the latin 'fibra', meaning a thread or filament, which itself likely originates from the proto-indo-european root dʰeh₁-, meaning to suck or to suckle, metaphorically extended to things that are drawn out like threads. the second element, '-osis', is a greek suffix adopted into latin and scientific english to denote a pathological state or condition. thus, the word's literal construction, "a condition of fibers," directly and logically describes the hallmark of the disease: the abnormal formation and accumulation of tough, thread-like collagen fibers within tissues, impairing their normal function.

Structure: fibr (fiber) + osis (condition) fibr: from latin 'fibra', meaning a filament, fiber, thread. in this word, it denotes fibrous tissue. osis: a suffix of greek origin (via latin '-osis'), indicating a process, condition, or state, often an abnormal or diseased one.
