A Roman's managed to transport ability to row (11)
I believe the answer is:
oarsmanship
'ability to row' is the definition.
I can't tell whether this defines the answer.
'a roman's managed to transport' is the wordplay.
'managed' indicates anagramming the letters.
'to transport' becomes 'ship' (synonyms).
'a'+'romans'='aromans'
'aromans' with letters rearranged gives 'oarsman'.
'oarsman'+'ship'='OARSMANSHIP'
Can you help me to learn more?
(Other definitions for oarsmanship that I've seen before include "Rowing skill" , "crafty skill" , "Rowers provide" .)
