Origin

Middle English (in the sense ‘cask’): from medieval Latin flasca. From the mid 16th century the word denoted a case of horn, leather, or metal for carrying gunpowder. The sense ‘glass container’ (late 17th century) was influenced by Italian fiasco, from medieval Latin flasco. Compare with flagon.
