Jewish skullcap (8)
I believe the answer is:
yarmulke
'jewish skullcap' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for yarmulke that I've seen before include "Jewish skullcap; leaky rum (anag.)" , "Jewish headgear" , "A skullcap worn by Jewish men" , "A Jewish man's skullcap" , "Skullcap worn by Jewish man" .)
