Vagabond, Romeo no more (5)
I believe the answer is:
rover
'vagabond' is the definition.
(thesaurus)
'romeo no more' is the wordplay.
'romeo' becomes 'r' (phonetic alphabet: alpha, bravo, charlie etc.).
'no more' becomes 'over' (I've seen this before).
'r'+'over'='ROVER'
(Other definitions for rover that I've seen before include "pirate ship" , "Pirate; dog's name" , "Car - dog" , "Nomad" , "One who wanders about" .)
