disease
UK: dɪˈziːz | US: dɪˈziːz
n. a disorder of structure or function in a human, animal, or plant, especially one that produces specific symptoms
n. (archaic) lack of ease; discomfort
The word "disease" originates from Middle English disese, combining the prefix dis- (meaning "absence of" or "opposite of") and ease (meaning "comfort" or "freedom from pain"). Originally, it broadly referred to any state of discomfort or unease. Over time, its meaning narrowed to specifically denote a medical condition disrupting normal bodily function. The evolution reflects a shift from general discomfort to a focused medical term, retaining the core idea of "lack of ease."
