Possibly borrowed from Albanian kësulë (var. kaçule). Alternatively cognate to it as Balkan substratum word, or akin to Latin casula or cuculla. Other attempts have been made to link it to a Latin *catteula, from *cattea, from cattus, to *casibula, variant of casubula, but these are unlikely. Compare also Venetian caciòła.
