I am very grateful that an explanation for pants and trousers is also included- that's another one.
Here everything like a cowboy hat, a Homburg, a trilby and a bowler would also be hats- but baseball caps would never. So the English hat invades the territory of the German cap- but basically it's the same difference

Killearn Karen: what you are talking about- would it be that classical thing made of Harris Tweed that has a short hard visor which is mainly hidden by the rest of the cap?
