Panache (French pronunciation: [panaʃ]) is a word of French origin that carries the connotation of flamboyant manner and reckless courage, derived from the helmet-plume worn by cavalrymen in the Early Modern period.[1]
The literal translation is a plume, such as is worn on a hat or a helmet; the reference is to King Henry IV of France (13 December 1553 – 14 May 1610), a pleasure-loving and cynical military leader, famed for wearing a striking white plume in his helmet and for his war cry: "Follow my white plume!" (French: Ralliez-vous à mon panache blanc!).
