Czapka
Czapka (, plural: czapki) is a Polish and Belarusian generic word for a cap. However, it is perhaps best known to English speakers as a word for the 19th-century Polish cavalry headgear, consisting of a high, four-pointed cap with regimental insignia on the front (full name in Polish: czapka rogatywka, initially: konfederatka) to which feathers or rosettes were sometimes added.
