disease

disease: [14] Disease and malaise are parallel formations: both denote etymologically an ‘impairment of ease or comfort’. Disease comes from Old French desaise, a compound formed from the prefix dis- ‘not, lacking’ and aise ‘ease’, and in fact at first meant literally ‘discomfort’ or ‘uneasiness’. It was only towards the end of the 14th century that this sense began to narrow down in English to ‘sickness’. (Malaise was borrowed from French malaise, an Old French formation from mal ‘bad’ and aise.)
=> ease, malaise

disease (n.)

early 14c., "discomfort, inconvenience," from Old French desaise "lack, want; discomfort, distress; trouble, misfortune; disease, sickness," from des- "without, away" (see dis-) + aise "ease" (see ease). Sense of "sickness, illness" in English first recorded late 14c.; the word still sometimes was used in its literal sense early 17c.
