Marshal cares about a conqueror of Gaul (6)
I believe the answer is:
caesar
'conqueror of gaul' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'marshal cares about a' is the wordplay.
'marshal' indicates an anagram (I've seen 'marshals' mean this (marshal can mean to gather)).
'about' indicates putting letters inside.
'cares' with letters rearranged gives 'cesar'.
'cesar' going around 'a' is 'CAESAR'.
Can you help me to learn more?
(Other definitions for caesar that I've seen before include "Title of the Roman emperors" , "Roman chief like Julius" , "See 12" , "leader who acts like a dictator" , "Emperor of ancient Rome, like Julius" .)
