Very interesting you use 1 word.....What is the etymology of priglavke?
I just know that the word “priglavke” (plural) is used for traditional wool slippers made by knitting. Priglavke were usually knitted by our grandmothers, so I’m afraid that this tradition could die out.
Zokni (masc. pl.) and its variant zokne (fem. pl.) both mean socks in general.
In Bulgarian it's дебели чорапи literally "fat socks"
In Bulgarian those are called терлици/terlitsi.
