Force English zealot, initially, to Moroccan city (3)
I believe the answer is:
fez
'moroccan city' is the definition.
(I've seen this before)
'force english zealot initially' is the wordplay.
'initially' suggests taking the first letters.
The initial letters of 'force english zealot' is 'FEZ'.
'to' is the link.
(Other definitions for fez that I've seen before include "Egyptian tasseled hat" , "Eastern felt cap with a tassel" , "Tarboosh" , "Hat - Moroccan city" , "Felt hat" .)
