Conqueror of Gaul gets a scare, perhaps (6)
I believe the answer is:
caesar
'conqueror of gaul' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'a scare perhaps' is the wordplay.
'perhaps' indicates anagramming the letters.
'a'+'scare'='ascare'
'ascare' anagrammed gives 'CAESAR'.
'gets' acts as a link.
Can you help me to learn more?
(Other definitions for caesar that I've seen before include "Eg, Augustus, Julius" , "He was killed during the Ides of March" , "See 2" , "Top man" , "Roman dictator" .)
