Working more outside for every ruler (7)
I believe the answer is:
emperor
'ruler' is the definition.
(I know that emperor is a type of crowned head)
'working more outside for every' is the wordplay.
'working' is an anagram indicator.
'outside' indicates putting letters inside (some letters go outside others).
'for every' becomes 'per' ('per' means 'for each' or 'for every').
'more' with letters rearranged gives 'emor'.
'emor' going around 'per' is 'EMPEROR'.
(Other definitions for emperor that I've seen before include "noted by Beethoven" , "Japanese version of the king" , "Napoleon Bonaparte, for instance" , "Roman leader" , "Ancient Roman ruler" .)
