A potential route — bravo! (3,2,2)
I believe the answer is:
way to go
'a potential' is the definition.
I know nothing about this answer so I can't judge whether this works.
'route bravo' is the wordplay.
'route' becomes 'way' (way is a kind of route).
'bravo' becomes 'togo' (I can't justify this - if you can you should believe this answer much more).
'way'+'togo'='WAY TO GO'
Can you help me to learn more?
(Other definitions for way to go that I've seen before include "Expression of US approval" , "Amazing" , "give American encouragement" , "expression of praise" , "Director gives one" .)
