caul

From Middle English calle, kelle, kalle, kolle (“caul, net, basket”), from Old English cāwl, cāul, cēawl, cēaul (“basket, container, net, sieve”), of uncertain origin. Reinforced by Old French cale (“close-fitting cap”), possibly a borrowing of the Old English term above, or alternatively related to Old French calotte (“headdress”), from Italian callotta, from Latin calautica (“type of female headdress which fell down over the shoulders”), itself of unknown origin. Cognate with Scots kell (“caul”).
