Romeo with every single one making pass (5)
I believe the answer is:
reach
'pass' is the definition.
(synonyms)
'romeo with every single one' is the wordplay.
'romeo' becomes 'R' (phonetic alphabet: alpha, bravo, charlie etc.).
'with' is a charade indicator (letters next to each other).
'every single one' becomes 'each' (I've seen this before).
'r'+'each'='REACH'
'making' is the link.
(Other definitions for reach that I've seen before include "It's an advantage for a boxer" , "Arrive at a point" , "Be received" , "Get in touch" , "Hit" .)
