Romeo and friend get better (5)
I believe the answer is:
rally
'get better' is the definition.
(thesaurus)
'romeo and friend' is the wordplay.
'romeo' becomes 'r' (phonetic alphabet: alpha, bravo, charlie etc.).
'and' says to put letters next to each other.
'friend' becomes 'ally' (I've seen this before).
'r'+'ally'='RALLY'
(Other definitions for rally that I've seen before include "Arouse for action" , "exchange over the Net?" , "Revive - motoring contest" , "(Of shares) increase after a fall" , "Recuperate in gathering" .)
