Old Roman vehicle bypassing deep track (6)
I believe the answer is:
brutus
'old roman' is the definition.
'brutus' can be an answer for 'roman' (I have seen 'Honourable Roman' mean 'brutus' so perhaps 'roman' could also mean 'brutus'). I am unsure of the 'old' bit.
'vehicle bypassing deep track' is the wordplay.
'vehicle' becomes 'bus' (bus is a kind of vehicle).
'bypassing' is an insertion indicator (I've seen this in other clues).
'deep track' becomes 'rut' (I've seen this before).
'bus' enclosing 'rut' is 'BRUTUS'.
Can you help me to learn more?
(Other definitions for brutus that I've seen before include "statesman who committed suicide in Macedonia" , "Caesar's assassin" , "legendary hero" , "One of Julius Caesar's assassins" , "Conspirator in the murder of Julius Caesar" .)
