Popular pro (2,6)
I believe the answer is:
in favour
I believe this is a double definition.
'popular' is the first definition.
(I've seen this before)
'pro' is the second definition.
(I've seen this before)
(Other definitions for in favour that I've seen before include "Pro" , "Highly regarded" , "Approved of" , "What persona grata would be" , "Popular" .)
