pantalones 29
In principle it would be the plural of pants, but it turns out that this garment is symmetrical because it is placed covering totally or partially both legs, and it is one of the cases in which the plural is also used to name a single object that seems to be formed by two parts. See canvases (lunfardo), Pantalone ("character of the Comedy of Art"), Pantaleon (remote origin of 'trousers').
