Etymology : “Sudden attack, convulsion,” early 15th century, from Middle French paroxysme (16th century), earlier paroxime (13th century), from Medieval Latin paroxysmus “irritation, fit of a disease,” from Greek paroxysmos “irritation, exasperation,” from paroxynein “to irritate, goad, provoke,” from para- “beyond” + oxynein “sharpen, goad,” from oxys “sharp, pointed”. Non-medical sense first attested circa 1600.
