atrophy
UK: ˈætrəfi | US: ˈætrəfi
n. the wasting away or degeneration of an organ or tissue due to lack of use, disease, or malnutrition
vi. to gradually decline in effectiveness or vigor due to neglect or disuse
The word "atrophy" originates from Greek atrophia, combining a- (meaning "without") and trophē (meaning "nourishment"). It literally describes a state of "lack of nourishment," reflecting the biological process where tissues weaken from insufficient sustenance or inactivity. Over time, its meaning expanded metaphorically to describe decline in non-physical contexts (e.g., skills or institutions).
