Five Turkish and British commanders in Rover (8)
I believe the answer is:
vagabond
'rover' is the definition.
(vagabond is a kind of rover)
'five turkish and british commanders' is the wordplay.
I cannot really see how this works, but
'five' could be 'v' (Roman numeral) and 'v' is found in the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is present in the answer.
'british' could be 'b' (abbreviation e.g. in BBC) and 'b' is found in the answer.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for vagabond that I've seen before include "Down-and-out" , "One wandering" , "An idle or dishonest wanderer" , "An idle or dishonest vagrant" , "Roving" .)
