Mosque part (7)
I believe the answer is:
minaret
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">mosque part</span>' is the definition.<br/ ><span class="explanation-format__explanation">('minaret' is part of 'mosque')</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for minaret that I've seen before include "religious tower" , "Mosque turret" , "tower in Istanbul, say" , "Slim tower of a mosque" , "Mosque's tower" .)
