disease:
early 14c., "discomfort, inconvenience, distress, trouble," from Old French desaise "lack, want; discomfort, distress; trouble, misfortune; disease, sickness," from des- "without, away" (see dis-) + aise "ease"
Discussion
mid-14c., disesen, "to make uneasy, trouble; inflict pain," a sense now obsolete; late 14c. as "to have an illness or infection;" late 15c. in the transitive sense of "to infect with a disease, make ill;" from disease (n.). Tyndale (1526) has Thy doughter is deed, disease not the master where KJV has trouble not (Luke viii.49).
