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" (see ease (n.)). Restricted pathological sense of "sickness, illness" in English emerged by late 14c.; the word still sometimes was used in its literal sense early 17c., and was somewhat revived 20c., usually with a hyphen (dis-ease).
late 14c., originally of fevers and diseases, "coming quickly to a crisis" (opposed to chronic), from Latin acutus "sharp, pointed," figuratively "shrill, penetrating; intelligent, cunning," past participle of acuere "to sharpen" (literal and figurative), from PIE root *ak- "be sharp, rise (out) to a point, pierce."
It was also used of humors (early 15c.). The meaning "ending in a sharp point" is from 1560s; the sense of "sharp or penetrating in intellect" is from 1580s. Of feelings, pains, etc., "intense," 1727. As a noun, early 15c. of fevers; c. 1600 as "an acute accent." Related: Acutely; acuteness.
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).
