Papa rents suits (7)
I believe the answer is:
pleases
'suits' is the definition.
(I've seen this in another clue)
'papa rents' is the wordplay.
'papa' becomes 'P' (phonetic alphabet: alpha, bravo, charlie etc.).
'rents' becomes 'leases' (I've seen this in another clue).
'p'+'leases'='PLEASES'
(Other definitions for pleases that I've seen before include "satisfies" , "Makes happy or satisfied" , "Delights" , "Gives satisfaction" .)
